RedirectToAction to the same action but without the route values

I'll show what I'm trying to do with a simple example.

I have the routes

routes.MapRoute("", 
                "Message", 
                new { controller = "Home", action = "Index", myEnum = MyEnum.Message});

routes.MapRoute("", 
                "", 
                new { controller = "Home", action = "Index" });

And the action

public ActionResult Index(/*other values*/, MyEnum? myEnum = null)
{
   // do some logic

   var redirectToHomeUrl = userLoggedIn && myEnum.HasValue && myEnum.Value == MyEnum.Message;

   if (redirectToHomeUrl)
   {
      // do some logic
      return RedirectToAction("Index"); <-- problem here
   }

   // Other logic
}

Basically the user gets sent to mysite.com/Message and is logged out and shown a model dialogue message over the home page. When they act on this message and log back in, the page reloads. I detect that they still have the url for the message and want to redirect them back to the home url "mysite.com/".

However return RedirectToAction("Index") still retains myEnum = MyEnum.Message.

RouteData is persisted after the redirect so I get an infinite loop.

I've tried RedirectToRoute(null, new { action = "Index", controller = "Home"});

I've tried RedirectToAction("Index", new {})

I've tried RouteData.Values.Clear()

I've tried RouteData.Values["myEnum"] = null;

If your wondering RedirectToAction("Index", new { myEnum = null }) doesn't compile :)

Any idea's on how to redirect to the same Action but removing existing route values?

Cheers in advance.

RedirectToAction("Index", new { myEnum = null })

might not compile, but this does:

RedirectToAction("Index", new { myEnum = (MyEnum?)null })

if you're wondering :)

I don't get the point of redirecting to the same action though. If all you want is to remove a value, set it to null manually (or ignore it). If you actually want to call a different function (but the same action) (doesn't seem to be the case, but who knows), just return that function's result from yours directly.
