I need to render an ASP page to a string from an MVC controller action. I can use Server.Execute() to render a .aspx page, but not a .asp page.

Here's what I'm using:

    public ActionResult Index()
    {
        Server.Execute("/default.asp");
        return new EmptyResult();
    }

which returns

`No http handler was found for request type 'GET'`

Any suggestions? I can do something similar with with a web request, but I'd rather avoid the overhead of a loopback request.
