title: ASP.NET MVC: url routing vs querystring
body: <p>I have a page routed like <code>/Comments/Search/3</code> where i search and display all the comments of the thread "3".</p>
  
  <p>I'm adding a sort function (by date, author etc). What is the best way to handle it? <code>/Comments/Search/3/Sort/Author</code> or <code>/Comments/Search/3?sort=author</code> ?</p>
  
  <p>How do I automatically handle the querystring sort=author as a parameter in MVC?</p>
  
  <p>Thanks</p>
