transfer sitemap.xml http request to route handler in ASP.NET MVC

I'm trying to add a route that will transfer all sitemap.xml requests to a custom request handler I made.

I tried using the following code:

        routes.Add(new Route("sitemap.xml", new Helpers.SiteMapRouteHandler()));
        routes.MapRoute(
            "Default",                                              
            "{controller}/{action}/{id}",                           
            new { controller = "Home", action = "Index", id = "" }  
        );

But when I make a link using Url.Action():

Url.Action("Index", new { controller = "About"})

I get the following when I try to navigate to the XML file:

/si开发者_JS百科temap.xml?action=Index&controller=About

What am I doing wrong?

I used this solution:

If you want to route to and action instead to a request handler

You could add a route like this

routes.MapRoute(
        "Sitemap",
        "sitemap.xml",
        new { controller = "Home", action = "SiteMap" }
        );

as mentioned here - MVC: How to route /sitemap.xml to an ActionResult? and it worked for me

Update: Also ensure that <modules runAllManagedModulesForAllRequests="true"> is set.

I'm not sure if this will solve the problem, but it's worth a try:

routes.Add(
    new Route(
        "{request}",
        new RouteValueDictionary(new { id = "" }),  // this might be the tricky part to change
        new RouteValueDictionary(new { request = "sitemap.xml" }),
        new Helpers.SiteMapRouteHandler()
    ));

You have to add a handler to web.config file.

<add name="SitemapFileHandler" path="sitemap.xml" verb="GET" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0"/>

And configure your routes:

routes.RouteExistingFiles = true;
