Parse MVC route custom file extension from RequestContext

Question

I have set up two custom extensions to enable MVC in IIS6.

So the site can be accessed with a URL of either something like...

mysite/mycontroller.europe/myaction

or like...

mysite/mycontroller.america/myaction

What is the most robust way of finding the extension from the RequestContext instance?

So I would like to be able to write something like...

var location = reqContext.......GetExtenstion(); // location = "europe"

and obviously have that work even if the setup of the site/directories changes a little.

Define a route:

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

and then:

var extension = RequestContext.RouteData.GetRequiredString("extension");
