title: facebook redirect entering an endless loop
body: <p>I am using v 5 RC and the CSMvc3FacebookApp.sln sample.</p>
  
  <p>When I launch the site locally (using IIS Express as WebServer) by browsing to:
  <a href="http://apps.facebook.com/myTestApp" rel="nofollow">http://apps.facebook.com/myTestApp</a>
  HomeController/Index View shows up properly. This means that the facebook settings are correct.</p>
  
  <p>However when I hit the 'About' link (this is where the facebook calls are made) I see an endless loop occur between:</p>
  
  <p><a href="http://apps.facebook.com/santiagoit/Home/About" rel="nofollow">http://apps.facebook.com/santiagoit/Home/About</a> 
  <a href="http://localhost:16874/facebookredirect.axd?code=" rel="nofollow">http://localhost:16874/facebookredirect.axd?code=</a></p>
  
  <p>If the user is not logged in to facebook. Hitting the 'About' link brings up the facebook login page, endless redirect loop happens after user signs in to facebook.</p>
  
  <p>I tested other sample projects and they behave the same.
  I tested with another facebook test app and same results.</p>
  
  <p>I had done a project with the older facebook developer toolkit, but I am new to this SDK.</p>
  
  <p>Any ideas what is going on?</p>
  
  <p>Thank you!</p>
