title: Create short permalinks similar to Stack Overflow's "short permalink to this question"
body: <p>I think I might already understand how this works, but wanted to be sure.</p>
  
  <p>I am in the process of defining the routes for a new ASP.NET MVC application. I'd like to create short permalinks similar to Stack Overflow's <em>short permalink to this question</em>: </p>

  <p>What route and controller mechanism is Stack Overflow using for this permalink behavior?</p>
