How to: SSL support
SSL mode (by default none) can be set to `auto` (ACME/LE certificates), `static` (existing certificate) or `none`. If `auto` turned on SSL certificate will be issued automatically for all discovered server names. User can override it by setting `--ssl.fqdn` value(s). In `auto` and `static` SSL mode, Reproxy will automatically add the `X-Forwarded-Proto` and `X-Forwarded-Port` headers. These headers are useful for services behind the proxy to know the original protocol (http or https) and port number used by the client.

When using ACME with discovery providers (docker, file, consul), SSL certificates are automatically obtained for newly discovered servers without requiring a reproxy restart.
