title: Different default page in MVC if authenticated
body: <p>This might be a very simple question, but I have a hard time to understand the MVC routing.</p>
  
  <p>Scenario: The user enters my site by entering www.mydomain.com in his browser. I would like to redirect to different default pages depending on if the user is authenticated or not.</p>
  
  <p>My current authentication approach: In Application_PostAuthenticateRequest I check for a FormsAuthentication cookie. If found I parse user principal from cookie.</p>
  
  <p>Where and how should I configure the redirect?</p>
