How can I redirect an existing ASP.NET MVC route to another (using HTTP 301)?

Question

I have a route:

    routes.MapRoute(
        "Company",
        "{id}/{name}.aspx",
        new { controller = "Company", action = "CompanyIndex" }
        );

I need redirect to the same URL, but without ".aspx" extension:

    routes.MapRoute(
        "Company",
        "{id}/{name}",
        new { controller = "Company", action = "CompanyIndex" }
        );

But the old URL (with aspx extension) can't return 404 error code. It just need redirect using 301 permanent redirect.

Create a redirection handler. http://msmvps.com/blogs/shahed/archive/2009/05/19/asp-net-mvc-tips-301-redirect-non-www-versions-of-url-to-www.aspx
