        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).

If you do not provide an encryption key, then the disk will be encrypted using an automatically generated key and you do not need to provide a key to use the disk later. Note: Instance templates do not store customer-supplied encryption keys, so you cannot use your own keys to encrypt disks in a managed instance group.

This filter is used to select a specific TimeSeries for the purpose of autoscaling and to determine whether the metric is exporting per-instance or per-group data. For the filter to be valid for autoscaling purposes, the following rules apply: - You can only use the AND operator for joining selectors. - You can only use direct equality comparison operator (=) without any functions for each selector. - You can specify the metric in both the filter string and in the metric field. However, if specified in both places, the metric must be identical. - The monitored resource type determines what kind of values are expected for the metric. If it is a gce_instance, the autoscaler expects the metric to include a separate TimeSeries for each instance in a group. In such a case, you cannot filter on resource labels. If the resource type is any other value, the autoscaler expects this metric to contain values that apply to the entire autoscaled instance group and resource label filtering can be performed to point autoscaler at the correct TimeSeries to scale upon. This is called a *per-group metric* for the purpose of autoscaling. If not specified, the type defaults to gce_instance. Try to provide a filter that is selective enough to pick just one TimeSeries for the autoscaled group or for each of the instances (if you are using gce_instance resource type). If multiple TimeSeries are returned upon the query execution, the autoscaler will sum their respective values to obtain its scaling value.

A good metric to use with the target is for example pubsub.googleapis.com/subscription/num_undelivered_messages or a custom metric exporting the total number of requests coming to your instances. A bad example would be a metric exporting an average or median latency, since this value can't include a chunk assignable to a single instance, it could be better used with utilization_target instead.

Setting a TTL of "0" means "always revalidate". The value of defaultTTL cannot be set to a value greater than that of maxTTL, but can be equal. When the cacheMode is set to FORCE_CACHE_ALL, the defaultTTL will overwrite the TTL set in all responses. The maximum allowed value is 31,622,400s (1 year), noting that infrequently accessed objects may be evicted from the cache before the defined TTL.
        # @!attribute [rw] max_ttl

        # @!attribute [rw] negative_caching
        #   @return [::Boolean]
        #     Negative caching allows per-status code TTLs to be set, in order to apply fine-grained caching for common errors or redirects. This can reduce the load on your origin and improve end-user experience by reducing response latency. When the cache mode is set to CACHE_ALL_STATIC or USE_ORIGIN_HEADERS, negative caching applies to responses with the specified response code that lack any Cache-Control, Expires, or Pragma: no-cache directives. When the cache mode is set to FORCE_CACHE_ALL, negative caching applies to all responses with the specified response code, and override any caching headers. By default, Cloud CDN will apply the following default TTLs to these status codes: HTTP 300 (Multiple Choice), 301, 308 (Permanent Redirects): 10m HTTP 404 (Not Found), 410 (Gone), 451 (Unavailable For Legal Reasons): 120s HTTP 405 (Method Not Found), 501 (Not Implemented): 60s. These defaults can be overridden in negative_caching_policy.

Omitting the policy and leaving negative_caching enabled will use Cloud CDN's default cache TTLs. Note that when specifying an explicit negative_caching_policy, you should take care to specify a cache TTL for all response codes that you wish to cache. Cloud CDN will not apply any default negative caching when a policy exists.

This setting defines the default "max-stale" duration for any cached responses that do not specify a max-stale directive. Stale responses that exceed the TTL configured here will not be served. The default limit (max-stale) is 86400s (1 day), which will allow stale content to be served up to this limit beyond the max-age (or s-maxage) of a cached response. The maximum allowed value is 604800 (1 week). Set this to zero (0) to disable serve-while-stale.

This is the default. - LEAST_REQUEST: An O(1) algorithm which selects two random healthy hosts and picks the host which has fewer active requests. - RING_HASH: The ring/modulo hash load balancer implements consistent hashing to backends. The algorithm has the property that the addition/removal of a host from a set of N hosts only affects 1/N of the requests. - RANDOM: The load balancer selects a random healthy host. - ORIGINAL_DESTINATION: Backend host is selected based on the client connection metadata, i.e., connections are opened to the same address as the destination address of the incoming connection before the connection was redirected to the load balancer. - MAGLEV: used as a drop in replacement for the ring hash load balancer. Maglev is not as stable as ring hash but has faster table lookup build times and host selection times. For more information about Maglev, see Maglev: A Fast and Reliable Software Network Load Balancer. - WEIGHTED_ROUND_ROBIN: Per-endpoint Weighted Round Robin Load Balancing using weights computed from Backend reported Custom Metrics. If set, the Backend Service responses are expected to contain non-standard HTTP response header field Endpoint-Load-Metrics. The reported metrics to use for computing the weights are specified via the customMetrics field. This field is applicable to either: - A regional backend service with the service_protocol set to HTTP, HTTPS, HTTP2 or H2C, and load_balancing_scheme set to INTERNAL_MANAGED. - A global backend service with the load_balancing_scheme set to INTERNAL_SELF_MANAGED, INTERNAL_MANAGED, or EXTERNAL_MANAGED. If sessionAffinity is not configured—that is, if session affinity remains at the default value of NONE—then the default value for localityLbPolicy is ROUND_ROBIN. If session affinity is set to a value other than NONE, then the default value for localityLbPolicy is MAGLEV. Only ROUND_ROBIN and RING_HASH are supported when the backend service is referenced by a URL map that is bound to target gRPC proxy that has validateForProxyless field set to true. localityLbPolicy cannot be specified with haPolicy.

Results of the outlier detection algorithm (ejection of endpoints from the load balancing pool and returning them back to the pool) are executed independently by each proxy instance of the load balancer. In most cases, more than one proxy instance handles the traffic received by a backend service. Thus, it is possible that an unhealthy endpoint is detected and ejected by only some of the proxies, and while this happens, other proxies may continue to send requests to the same unhealthy endpoint until they detect and eject the unhealthy endpoint. Applicable backend endpoints can be: - VM instances in an Instance Group - Endpoints in a Zonal NEG (GCE_VM_IP, GCE_VM_IP_PORT) - Endpoints in a Hybrid Connectivity NEG (NON_GCP_PRIVATE_IP_PORT) - Serverless NEGs, that resolve to Cloud Run, App Engine, or Cloud Functions Services - Private Service Connect NEGs, that resolve to Google-managed regional API endpoints or managed services published using Private Service Connect Applicable backend service types can be: - A global backend service with the loadBalancingScheme set to INTERNAL_SELF_MANAGED or EXTERNAL_MANAGED. - A regional backend service with the serviceProtocol set to HTTP, HTTPS, HTTP2 or H2C, and loadBalancingScheme set to INTERNAL_MANAGED or EXTERNAL_MANAGED.

Responses without these headers will not be cached at Google's edge, and will require a full trip to the origin on every request, potentially impacting performance and increasing load on the origin server. FORCE_CACHE_ALL Cache all content, ignoring any "private", "no-store" or "no-cache" directives in Cache-Control response headers. Warning: this may result in Cloud CDN caching private, per-user (user identifiable) content.

With FORCE_CACHE_ALL, the lesser of client_ttl and default_ttl is used for the response max-age directive, along with a "public" directive. For cacheable content in CACHE_ALL_STATIC mode, client_ttl clamps the max-age from the origin (if specified), or else sets the response max-age directive to the lesser of the client_ttl and default_ttl, and also ensures a "public" cache-control directive is present. If a client TTL is not specified, a default value (1 hour) will be used. The maximum allowed value is 31,622,400s (1 year).

When the cacheMode is set to FORCE_CACHE_ALL, the defaultTTL will overwrite the TTL set in all responses.

This can reduce the load on your origin and improve end-user experience by reducing response latency. When the cache mode is set to CACHE_ALL_STATIC or USE_ORIGIN_HEADERS, negative caching applies to responses with the specified response code that lack any Cache-Control, Expires, or Pragma: no-cache directives. When the cache mode is set to FORCE_CACHE_ALL, negative caching applies to all responses with the specified response code, and override any caching headers. By default, Cloud CDN will apply the following default TTLs to these status codes: HTTP 300 (Multiple Choice), 301, 308 (Permanent Redirects): 10m HTTP 404 (Not Found), 410 (Gone), 451 (Unavailable For Legal Reasons): 120s HTTP 405 (Method Not Found), 501 (Not Implemented): 60s. These defaults can be overridden in negative_caching_policy.

This setting defines the default "max-stale" duration for any cached responses that do not specify a max-stale directive. Stale responses that exceed the TTL configured here will not be served. The default limit (max-stale) is 86400s (1 day), which will allow stale content to be served up to this limit beyond the max-age (or s-maxage) of a cached response. The maximum allowed value is 604800 (1 week). Set this to zero (0) to disable serve-while-stale.

        #   @return [::String]
        #     Specifies whether fast IP move is enabled, and if so, the mechanism to achieve it. Supported values are: - DISABLED: Fast IP Move is disabled. You can only use the haPolicy.leader API to update the leader. - >GARP_RA: Provides a method to very quickly define a new network endpoint as the leader. This method is faster than updating the leader using the haPolicy.leader API. Fast IP move works as follows: The VM hosting the network endpoint that should become the new leader sends either a Gratuitous ARP (GARP) packet (IPv4) or an ICMPv6 Router Advertisement(RA) packet (IPv6). Google Cloud immediately but temporarily associates the forwarding rule IP address with that VM, and both new and in-flight packets are quickly delivered to that VM. Note the important properties of the Fast IP Move functionality: - The GARP/RA-initiated re-routing stays active for approximately 20 minutes. After triggering fast failover, you must also appropriately set the haPolicy.leader. - The new leader instance should continue to send GARP/RA packets periodically every 10 seconds until at least 10 minutes after updating the haPolicy.leader (but stop immediately if it is no longer the leader). - After triggering a fast failover, we recommend that you wait at least 3 seconds before sending another GARP/RA packet from a different VM instance to avoid race conditions. - Don't send GARP/RA packets from different VM instances at the same time. If multiple instances continue to send GARP/RA packets, traffic might be routed to different destinations in an alternating order. This condition ceases when a single instance issues a GARP/RA packet. - The GARP/RA request always takes priority over the leader API. Using the haPolicy.leader API to change the leader to a different instance will have no effect until the GARP/RA request becomes inactive. - The GARP/RA packets should follow the GARP/RA Packet Specifications.. - When multiple forwarding rules refer to a regional backend service, you need only send a GARP or RA packet for a single forwarding rule virtual IP. The virtual IPs for all forwarding rules targeting the same backend service will also be moved to the sender of the GARP or RA packet. The following are the Fast IP Move limitations (that is, when fastIPMove is not DISABLED): - Multiple forwarding rules cannot use the same IP address if one of them refers to a regional backend service with fastIPMove. - The regional backend service must set the network field, and all NEGs must belong to that network. However, individual NEGs can belong to different subnetworks of that network. - The maximum number of network endpoints across all backends of a backend service with fastIPMove is 32. - The maximum number of backend services with fastIPMove that can have the same network endpoint attached to one of its backends is 64. - The maximum number of backend services with fastIPMove in a VPC in a region is 64. - The network endpoints that are attached to a backend of a backend service with fastIPMove cannot resolve to Gen3+ machines for IPv6. - Traffic directed to the leader by a static route next hop will not be redirected to a new leader by fast failover. Such traffic will only be redirected once an haPolicy.leader update has taken effect.

          # Specifies whether fast IP move is enabled, and if so, the mechanism to achieve it. Supported values are: - DISABLED: Fast IP Move is disabled. You can only use the haPolicy.leader API to update the leader. - >GARP_RA: Provides a method to very quickly define a new network endpoint as the leader. This method is faster than updating the leader using the haPolicy.leader API. Fast IP move works as follows: The VM hosting the network endpoint that should become the new leader sends either a Gratuitous ARP (GARP) packet (IPv4) or an ICMPv6 Router Advertisement(RA) packet (IPv6). Google Cloud immediately but temporarily associates the forwarding rule IP address with that VM, and both new and in-flight packets are quickly delivered to that VM. Note the important properties of the Fast IP Move functionality: - The GARP/RA-initiated re-routing stays active for approximately 20 minutes. After triggering fast failover, you must also appropriately set the haPolicy.leader. - The new leader instance should continue to send GARP/RA packets periodically every 10 seconds until at least 10 minutes after updating the haPolicy.leader (but stop immediately if it is no longer the leader). - After triggering a fast failover, we recommend that you wait at least 3 seconds before sending another GARP/RA packet from a different VM instance to avoid race conditions. - Don't send GARP/RA packets from different VM instances at the same time. If multiple instances continue to send GARP/RA packets, traffic might be routed to different destinations in an alternating order. This condition ceases when a single instance issues a GARP/RA packet. - The GARP/RA request always takes priority over the leader API. Using the haPolicy.leader API to change the leader to a different instance will have no effect until the GARP/RA request becomes inactive. - The GARP/RA packets should follow the GARP/RA Packet Specifications.. - When multiple forwarding rules refer to a regional backend service, you need only send a GARP or RA packet for a single forwarding rule virtual IP. The virtual IPs for all forwarding rules targeting the same backend service will also be moved to the sender of the GARP or RA packet. The following are the Fast IP Move limitations (that is, when fastIPMove is not DISABLED): - Multiple forwarding rules cannot use the same IP address if one of them refers to a regional backend service with fastIPMove. - The regional backend service must set the network field, and all NEGs must belong to that network. However, individual NEGs can belong to different subnetworks of that network. - The maximum number of network endpoints across all backends of a backend service with fastIPMove is 32. - The maximum number of backend services with fastIPMove that can have the same network endpoint attached to one of its backends is 64. - The maximum number of backend services with fastIPMove in a VPC in a region is 64. - The network endpoints that are attached to a backend of a backend service with fastIPMove cannot resolve to Gen3+ machines for IPv6. - Traffic directed to the leader by a static route next hop will not be redirected to a new leader by fast failover. Such traffic will only be redirected once an haPolicy.leader update has taken effect. Only traffic to the forwarding rule's virtual IP will be redirected to a new leader by fast failover. haPolicy.fastIPMove can be set only at backend service creation time. Once set, it cannot be updated. By default, fastIpMove is set to DISABLED.

Forwarding rules can also reference target instances and Cloud VPN Classic gateways (targetVpnGateway). For more information, read Forwarding rule concepts and Using protocol forwarding.
        # @!attribute [rw] I_p_address
        #   @return [::String]
        #     IP address for which this forwarding rule accepts traffic. When a client sends traffic to this IP address, the forwarding rule directs the traffic to the referenced target or backendService. While creating a forwarding rule, specifying an IPAddress is required under the following circumstances: - When the target is set to targetGrpcProxy and validateForProxyless is set to true, the IPAddress should be set to 0.0.0.0. - When the target is a Private Service Connect Google APIs bundle, you must specify an IPAddress. Otherwise, you can optionally specify an IP address that references an existing static (reserved) IP address resource. When omitted, Google Cloud assigns an ephemeral IP address. Use one of the following formats to specify an IP address while creating a forwarding rule: * IP address number, as in `100.1.2.3` * IPv6 address range, as in `2600:1234::/96` * Full resource URL, as in https://www.googleapis.com/compute/v1/projects/ project_id/regions/region/addresses/address-name * Partial URL or by name, as in: - projects/project_id/regions/region/addresses/address-name - regions/region/addresses/address-name - global/addresses/address-name - address-name The forwarding rule's target or backendService, and in most cases, also the loadBalancingScheme, determine the type of IP address that you can use. For detailed information, see [IP address specifications](https://cloud.google.com/load-balancing/docs/forwarding-rule-concepts#ip_address_specifications).

        # A request message for Routers.GetNatMappingInfo. See the method description for details.
        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

You can also sort results in descending order based on the creation timestamp using `orderBy="creationTimestamp desc"`. This sorts results based on the `creationTimestamp` field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by `name` or `creationTimestamp desc` is supported.

If the output for that byte position is available, this field matches the `start` parameter sent with the request. If the amount of serial console output exceeds the size of the buffer (1 MB), the oldest output is discarded and is no longer available. If the requested start position refers to discarded output, the start position is adjusted to the oldest output still available, and the adjusted start position is returned as the `start` property value. You can also provide a negative start position, which translates to the most recent number of bytes written to the serial port. For example, -3 is interpreted as the most recent 3 bytes written to the serial console. Note that the negative start is bounded by the retained buffer size, and the returned serial console output will not exceed the max buffer size.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.
        # @!attribute [rw] max_results

        #   @return [::String]

You can also sort results in descending order based on the creation timestamp using `orderBy="creationTimestamp desc"`. This sorts results based on the `creationTimestamp` field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by `name` or `creationTimestamp desc` is supported.
        # @!attribute [rw] page_token

For example, consider a UrlMap with the following configuration: - UrlMap.defaultCustomErrorResponsePolicy are configured with policies for 5xx and 4xx errors - A RouteRule for /coming_soon/ is configured for the error code 404. If the request is for www.myotherdomain.com and a 404 is encountered, the policy under UrlMap.defaultCustomErrorResponsePolicy takes effect. If a 404 response is encountered for the request www.example.com/current_events/, the pathMatcher's policy takes effect.

        # @!attribute [rw] priority
        #   @return [::Integer]
        #     For routeRules within a given pathMatcher, priority determines the order in which a load balancer interprets routeRules. RouteRules are evaluated in order of priority, from the lowest to highest number. The priority of a rule decreases as its number increases (1, 2, 3, N+1). The first rule that matches the request is applied. You cannot configure two or more routeRules with the same priority. Priority for each rule must be set to a number from 0 to 2147483647 inclusive. Priority numbers can have gaps, which enable you to add or remove rules in the future without affecting the rest of the rules. For example, 1, 2, 3, 4, 5, 9, 12, 16 is a valid series of priority numbers to which you could add rules numbered from 6 to 8, 10 to 11, and 13 to 15 in the future without any impact on existing rules.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by `name` or `creationTimestamp desc` is supported.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        # @!attribute [rw] filter
        #   @return [::String]
        #     A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`. You cannot combine constraints on multiple fields using regular expressions.

        #     defaultCustomErrorResponsePolicy specifies how the Load Balancer returns error responses when BackendServiceor BackendBucket responds with an error. This policy takes effect at the PathMatcher level and applies only when no policy has been defined for the error code at lower levels like RouteRule and PathRule within this PathMatcher. If an error code does not have a policy defined in defaultCustomErrorResponsePolicy, then a policy defined for the error code in UrlMap.defaultCustomErrorResponsePolicy takes effect. For example, consider a UrlMap with the following configuration: - UrlMap.defaultCustomErrorResponsePolicy is configured with policies for 5xx and 4xx errors - A RouteRule for /coming_soon/ is configured for the error code 404. If the request is for www.myotherdomain.com and a 404 is encountered, the policy under UrlMap.defaultCustomErrorResponsePolicy takes effect. If a 404 response is encountered for the request www.example.com/current_events/, the pathMatcher's policy takes effect. If however, the request for www.example.com/coming_soon/ encounters a 404, the policy in RouteRule.customErrorResponsePolicy takes effect. If any of the requests in this example encounter a 500 error code, the policy at UrlMap.defaultCustomErrorResponsePolicy takes effect. When used in conjunction with pathMatcher.defaultRouteAction.retryPolicy, retries take precedence. Only once all retries are exhausted, the defaultCustomErrorResponsePolicy is applied. While attempting a retry, if load balancer is successful in reaching the service, the defaultCustomErrorResponsePolicy is ignored and the response from the service is returned to the client. defaultCustomErrorResponsePolicy is supported only for global external Application Load Balancers.

        # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": [ "user:eve@example.com" ], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01T00:00:00.000Z')", } } ], "etag": "BwWWja0YfJA=", "version": 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time < timestamp('2020-10-01T00:00:00.000Z') etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).

        #     Associates a list of `members`, or principals, with a `role`. Optionally, may specify a `condition` that determines how and when the `bindings` are applied. Each of the `bindings` must contain at least one principal. The `bindings` in a `Policy` can refer to up to 1,500 principals; up to 250 of these principals can be Google groups. Each occurrence of a principal counts towards these limits. For example, if the `bindings` grant 50 different roles to `user:alice@example.com`, and not to any other principal, then you can add another 1,450 principals to the `bindings` in the `Policy`.
        # @!attribute [rw] etag
        #   @return [::String]
        #     `etag` is used for optimistic concurrency control as a way to help prevent simultaneous updates of a policy from overwriting each other. It is strongly suggested that systems make use of the `etag` in the read-modify-write cycle to perform policy updates in order to avoid race conditions: An `etag` is returned in the response to `getIamPolicy`, and systems are expected to put that etag in the request to `setIamPolicy` to ensure that their change will be applied to the same version of the policy. **Important:** If you use IAM Conditions, you must include the `etag` field whenever you call `setIamPolicy`. If you omit this field, then IAM allows you to overwrite a version `3` policy with a version `1` policy, and all of the conditions in the version `3` policy are lost.

        #   @return [::Integer]
        #     Specifies the format of the policy. Valid values are `0`, `1`, and `3`. Requests that specify an invalid value are rejected. Any operation that affects conditional role bindings must specify version `3`. This requirement applies to the following operations: * Getting a policy that includes a conditional role binding * Adding a conditional role binding to a policy * Changing a conditional role binding in a policy * Removing any role binding, with or without a condition, from a policy that includes conditions **Important:** If you use IAM Conditions, you must include the `etag` field whenever you call `setIamPolicy`. If you omit this field, then IAM allows you to overwrite a version `3` policy with a version `1` policy, and all of the conditions in the version `3` policy are lost. If a policy does not include any conditions, operations on that policy may specify any valid version or leave the field unset. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).

This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).

        #     A match condition that incoming packets are evaluated against for CLOUD_ARMOR_NETWORK security policies. If it matches, the corresponding 'action' is enforced. The match criteria for a rule consists of built-in match fields (like 'srcIpRanges') and potentially multiple user-defined match fields ('userDefinedFields'). Field values may be extracted directly from the packet or derived from it (e.g. 'srcRegionCodes'). Some fields may not be present in every packet (e.g. 'srcPorts'). A user-defined field is only present if the base header is found in the packet and the entire field is in bounds. Each match field may specify which values can match it, listing one or more ranges, prefixes, or exact values that are considered a match for the field. A field value must be present in order to match a specified match field. If no match values are specified for a match field, then any field value is considered to match it, and it's not required to be present. For strings specifying '*' is also equivalent to match all. For a packet to match a rule, all specified match fields must match the corresponding field values derived from the packet. Example: networkMatch: srcIpRanges: - "192.0.2.0/24" - "198.51.100.0/24" userDefinedFields: - name: "ipv4_fragment_offset" values: - "1-0x1fff" The above match condition matches packets with a source IP in 192.0.2.0/24 or 198.51.100.0/24 and a user-defined field named "ipv4_fragment_offset" with a value between 1 and 0x1fff inclusive.

Early Data allows a TLS resumption handshake to include the initial application payload (a HTTP request) alongside the handshake, reducing the effective round trips to "zero". This applies to TLS 1.3 connections over TCP (HTTP/2) as well as over UDP (QUIC/h3). This can improve application performance, especially on networks where interruptions may be common, such as on mobile. Requests with Early Data will have the "Early-Data" HTTP header set on the request, with a value of "1", to allow the backend to determine whether Early Data was included. Note: TLS Early Data may allow requests to be replayed, as the data is sent to the backend before the handshake has fully completed. Applications that allow idempotent HTTP methods to make non-idempotent changes, such as a GET request updating a database, should not accept Early Data on those requests, and reject requests with the "Early-Data: 1" HTTP header by returning a HTTP 425 (Too Early) status code, in order to remain RFC compliant.

        # Represents a URL Map resource. Compute Engine has two URL Map resources: * [Global](/compute/docs/reference/rest/v1/urlMaps) * [Regional](/compute/docs/reference/rest/v1/regionUrlMaps) A URL map resource is a component of certain types of cloud load balancers and Traffic Director: * urlMaps are used by global external Application Load Balancers, classic Application Load Balancers, and cross-region internal Application Load Balancers. * regionUrlMaps are used by internal Application Load Balancers, regional external Application Load Balancers and regional internal Application Load Balancers. For a list of supported URL map features by the load balancer type, see the Load balancing features: Routing and traffic management table. For a list of supported URL map features for Traffic Director, see the Traffic Director features: Routing and traffic management table. This resource defines mappings from hostnames and URL paths to either a backend service or a backend bucket. To use the global urlMaps resource, the backend service must have a loadBalancingScheme of either EXTERNAL, EXTERNAL_MANAGED, or INTERNAL_SELF_MANAGED. To use the regionUrlMaps resource, the backend service must have a loadBalancingScheme of INTERNAL_MANAGED. For more information, read URL Map Concepts.

        # @!attribute [rw] default_custom_error_response_policy
        #   @return [::Google::Cloud::Compute::V1::CustomErrorResponsePolicy]
        #     defaultCustomErrorResponsePolicy specifies how the Load Balancer returns error responses when BackendServiceor BackendBucket responds with an error. This policy takes effect at the load balancer level and applies only when no policy has been defined for the error code at lower levels like PathMatcher, RouteRule and PathRule within this UrlMap. For example, consider a UrlMap with the following configuration: - defaultCustomErrorResponsePolicy containing policies for responding to 5xx and 4xx errors - A PathMatcher configured for *.example.com has defaultCustomErrorResponsePolicy for 4xx. If a request for http://www.example.com/ encounters a 404, the policy in pathMatcher.defaultCustomErrorResponsePolicy will be enforced. When the request for http://www.example.com/ encounters a 502, the policy in UrlMap.defaultCustomErrorResponsePolicy will be enforced. When a request that does not match any host in *.example.com such as http://www.myotherexample.com/, encounters a 404, UrlMap.defaultCustomErrorResponsePolicy takes effect. When used in conjunction with defaultRouteAction.retryPolicy, retries take precedence. Only once all retries are exhausted, the defaultCustomErrorResponsePolicy is applied. While attempting a retry, if load balancer is successful in reaching the service, the defaultCustomErrorResponsePolicy is ignored and the response from the service is returned to the client. defaultCustomErrorResponsePolicy is supported only for global external Application Load Balancers.

The selection of a backend service is determined only for new traffic. Once a user's request has been directed to a backend service, subsequent requests are sent to the same backend service as determined by the backend service's session affinity policy. Don't configure session affinity if you're using weighted traffic splitting. If you do, the weighted traffic splitting configuration takes precedence. The value must be from 0 to 1000.
