title: CAS being ignored by ASP.NET 2.0 application in IIS 7, not ignored in Visual Studio server
body: <p>I've got an ASP.NET 2.0 application (references System.Web, etc., v. 2.0) using the .NET CAS client.  It works fine using the Web server built into Visual Studio, but when I deploy to IIS7, rather than using the CAS settings in Web.config to log in using my CAS url with the <code>service</code> query string parameter with the full URL (which happens during debugging), it uses <code>ReturnUrl</code> query string parameter as though it's doing regular old authentication.</p>
  
  <p>I'm not sure where to begin.  I haven't had luck getting anything out of log4net.</p>
  
  <p>Thanks!</p>
