Legacy URL rewriting with query string parameters

I've looked at ASP.Net MVC routing legacy URLs passing querystring Ids to controlle开发者_如何学Gor actions and several other similar posts for legacy URL routing, but I can't get past the error "The RouteData must contain an item named 'controller' with a non-empty string value." Looking this up on line didn't give me any hints to solve my problem.

I've implemented the Legacy routing class described in the link above, and this is what I've defined in the routing table:

        routes.Add(
            "Legacy", 
            new LegacyRoute("fooref.aspx", 
            "FooRef", 
            new LegacyRouteHandler())
        );

        routes.MapRoute(
            "FooRef",
            "{controller}/{action}",
            new
            {
                controller = "Home",
                action = "Index",
                foo_id = UrlParameter.Optional,
                bar_id = UrlParameter.Optional
            }
        );

When I use Phil Haack's route debugger, it indicates that fooref.aspx has a match, but when I turn the route debugger off, I get the error above. If I reverse the statement order, I get "Resource not found" for /ctprefer.aspx, which makes sense -- so it appears to be finding that as a valid route when put in the other order.

Where do I need to declare this missing controller reference?

Have routing requirements changed for ASP.NET MVC 2 RTM?

The solution to this is to use an IHttpHandler directly, rather than an MVCHandler. I have posted code that works with MVC 3 to my blog: http://www.olsonsoft.com/blogs/stefanolson/post/Handling-Legacy-Urls-in-AspNet-MVC-3.aspx

You might want to take a look at URL Rewrite module for IIS. It can be used to translate legacy URL to your new MVC URLs without 'polluting' your app with legacy routes.

Don't know if it will fit your solution but it's worth having an alternative.
