title: MVC controller gives me a 403 forbidden error with the default route when it's called DocumentationController
body: <p>Is <code>DocumentationController</code> reserved for system usage or something?</p>
  
  <p>I created a blank MVC app, created a DocumentationController with corresponding view. It works if I go to <code>www.mysite.com/Documentation/Index</code> but if I go to <code>www.mysite.com/Documentation/</code> then I get a 403 forbidden.</p>
  
  <p>Renaming <code>DocumentationController</code> to <code>Documentation2Controller</code> and associated views, it (the default route, etc.) works perfectly.</p>
  
  <p>Is it a reserved keyword or could there be another reason why it doesn't pick up the default route?</p>
