how to simulate IgnoreRoute in my custom MvcRouteHandler - asp.net

Question

In my ASP.NET MVC3 App I try simulate "routes.IgnoreRoute("...")"
I create CustomMvcRouteHandler:
public class CustomMvcRouteHandler: MvcRouteHandler
{
protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
{
// do something
....
return base.GetHttpHandler(requestContext);
}
}
in my Global.asax.cs file i have:
protected void Application_Start()
{
// ............
RegisterRoutes(RouteTable.Routes);
// ............
}
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("elmah.axd");
//routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
).RouteHandler = new CustomMvcRouteHandler();
}
How can I do this ?

Answer 1

I'm not entirely sure what you mean in your question, but I'll try to answer it...
To simulate an IgnoreRoute all you need to do is associate an instance of the StopRoutingHandler from your route. If you're using the built-in ASP.NET "Route" class then you would do something like this:
routes.MapRoute(
"Ignore-This", // Route name
"ignore/{this}/{pattern}" // URL with parameters
).RouteHandler = new StopRoutingHandler();
Anything that matches that pattern will cause the routing system to immediately stop processing any more routes.
If you want to write your own custom route (for example, a new route type that derives from RouteBase), then from its GetRouteData method you need to return the StopRoutingHandler.

#Eilon is the correct answer. Here is an alternative syntax that feels more MVCish.
routes.Add("Ignore-This",
new Route(
"ignore/{this}/{pattern}",
new StopRoutingHandler())
);
