title: MVC routing question
body: <p>I want to setup routing as follows:</p>
  
  <p>/Profile/Edit -> routes to Edit action</p>
  
  <p>/Profile/Add -> routes to Add action</p>
  
  <p>/Profile/username -> routes to Index action with parameter username, because action username doesn't exist.</p>
  
  <p>So I want the second parameter to be parsed as the controller action, except when no controller with that name exists; then it should route to the default index page and use the url part as id. </p>
  
  <p>Possible?</p>
