How can I properly handle 404 in ASP.NET MVC?

Question

I am using RC2

Using URL Routing:

routes.MapRoute(
    \"Error\",
     \"{*url}\",
     new { controller = \"Errors\", action = \"N

ASP.NET MVC doesn't support custom 404 pages very well. Custom controller factory, catch-all route, base controller class with HandleUnknownAction - argh!

IIS custom error pages are better alternative so far:

web.config

ErrorController

public class ErrorController : Controller
{
    public ActionResult PageNotFound()
    {
        Response.StatusCode = 404;
        return View();
    }
}
