<p>I'm using the <a href="http://msdn.microsoft.com/en-us/library/ms178329.aspx" rel="nofollow noreferrer">ASP.NET Login Controls</a> and <a href="http://msdn.microsoft.com/en-us/library/aa480476.aspx" rel="nofollow noreferrer">Forms Authentication</a> for membership/credentials for an ASP.NET web application.  It keeps redirecting to a Login.aspx page at the root of my application that does not exist.  My login page is within a folder.</p>

I found the answer at
CoderSource.net
.  I had to put the correct path into my web.config file.
```
```
<?xml version="1.0"?>
<configuration>
    <system.web>
        ...
        <!--
            The <authentication> section enables configuration 
            of the security authentication mode used by 
            ASP.NET to identify an incoming user. 
        -->
        <authentication mode="Forms">
            <forms loginUrl="~/FolderName/Login.aspx" />
        </authentication>
        ...
    </system.web>
    ...
</configuration>
```
```
