title: AOL OpenID response too long
body: <p>I've written an application using the DotNetOpenAuth library, which allows users to authenticate against a number of OpenID providers.  All of them work fine except for AOL, which for one reason or another creates a return URL that is over 2200 characters long, a length that exceeds the maximum URL length (2048) for most browsers.</p>
  
  <p>Has anyone experienced this?  Is there a way to limit the number of parameters (in particular, the dnoa-specific parameters) being passed through to the provider?</p>
  
  <p>The real problem is the "openid.return_to" parameter, which is a duplicate of the entire URL, but that's a problem with OpenID spec and consequently can't be easily rectified.</p>
  
  <p>Thank you for the assistance,
  Garrett</p>
