How to make routing in ASP.NET MVC3 Compatible in both IIS 6 and 7?

I have this code in Global.asax.cs:

 public static void RegisterRoutes(RouteCollection routes)
        {

            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                "Applications", // Route name 
                "Applications.aspx/Find/{appNum}", // URL with parameters 
                new
                {
                    controller = "Applications",
                    action = "Find"
                }, // Parameter defaults 
                new
                {
                    appNum = @"\d+"
                }  // Constraints
            );

            routes.MapRoute(
                "Default", // Route name
                "{controller}.aspx/{action}", // URL with parameters
                new
                {
                    controller = "Applications",
                    action = "Index"
                } // Parameter defaults
            );
        }

This is tuned to work for IIS 6: notice .aspx after {controller}

How can i make the same code work on both IIS 6 and IIS 7 without changing any on the IIS sid开发者_开发问答e?
