title: Pass Id and String to WebAPI Get
body: <p>Im using the New MVC Web Api I have something like this:</p>
  
  <pre><code>    public class CustomersController : ApiController
      {
    public HttpResponseMessage Get()
          {
              //Return Somethings
          }
      }
  </code></pre>
  
  <p>I call it with /api/customers</p>
  
  <p>now i want to be able to filter by nationality and id so i made this :</p>
  
  <pre><code>public class CustomersController : ApiController
  {
      public HttpResponseMessage Get(int Id, String Nat)
      {
          //and i filter here Return Somethings
      }
  }
  </code></pre>
  
  <p>if i try to use <code>/api/customers/1/us</code> it call the first method, i understand that these are query strings, so how do i define route so i can use <code>/api/customers/1/us</code> ?</p>
