title: Account for simple url rewriting in ASP.NET MVC redirect
body: <p>How would you go about redirecting in ASP.NET MVC to take into account some external URL rewriting rules.</p>
  
  <p>For example:</p>
  
  <ul>
  <li>What the user enters: <a href="http://www.example.com/app/route" rel="nofollow noreferrer">http://www.example.com/app/route</a></li>
  <li>What ASP.NET MVC sees: /route</li>
  <li>What I want to redirect to: <a href="http://www.example.com/app/other_route" rel="nofollow noreferrer">http://www.example.com/app/other_route</a></li>
  <li>What actually happens when I do a simple <a href="http://msdn.microsoft.com/en-us/library/dd460311.aspx" rel="nofollow noreferrer">RedirectToAction</a>: <a href="http://www.example.com/other_route" rel="nofollow noreferrer">http://www.example.com/other_route</a> (which doesn't exist, from the outside anyway)</li>
  </ul>
  
  <p>This seems like it should be simple, but I'm drawing a blank.</p>
