title: IRouteHandler not routing through RouteConfig
body: <p>I have a IRouteHander class which I use to resize images on the fly and add expire headers to them, Recently I moved to MVC5 and now updating my code. I tried to register the same route for that class in RouteConfig.cs </p>
  
  <pre><code>routes.Add(new Route("Image/{w}/{h}/{src}", new ThumbImageRouteHandler()));
  </code></pre>
  
  <p>but this route isn't working anymore like it was on MVC3 and giving 404 error in MVC5. Is there anything I am missing here? this route leads to </p>
  
  <pre><code>public class ThumbImageRouteHandler : IRouteHandler
  {
           public IHttpHandler GetHttpHandler(RequestContext requestContext)
              {
                  HttpHanler httpHandler = new HttpHanler();
                  return httpHandler;
              }
              public class HttpHanler : IHttpHandler
              {
                  public bool IsReusable
                  {
                      get
                      {
                          return false;
                      }
                  }
                  public void ProcessRequest(HttpContext context)
                  {
                  //Do something
                  }
                 }
             }
  }
