Ambient values in mvc2.net routing

Question

I have following two routes registered in my global.asax file

routes.MapRoute(
    \"strict\",
    \"{controller}.mvc/{docid}/{action}/{id}\",

My routing is defined this way:

routes.MapRoute(
    "Planning",
    "Plans/{plan}/{controller}/{action}/{identifier}",
    new { controller = "General", action = "Planning", identifier = UrlParameter.Optional },
    new { plan = @"^\d+$" }
);

// default application route
routes.MapRoute(
    "Default",
    "{controller}/{action}/{identifier}",
    new {
        controller = "General",
        action = "Summary",
        identifier = UrlParameter.Optional,
        plan = string.Empty // mind this default !!!
    }
);

This is very similar to what you're using. But mind my default route where I define defaults. Even though my default route doesn't define plan route value I still set it to string.Empty. So whenever I use Html.ActionLink() or Url.Action() and I want plan to be removed from the URL I call it the usual way:

Url.Action("Action", "Controller", new { plan = string.Empty });

And plan is not included in the URL query string any more. Try it out yourself it may work as well.
