How can I create a routing structure for a project management application where there are discrete controllers for all the relevant pieces such as TaskController, DocumentController etc and an Over arching controller. I would essentially like a structure like:

http://server/Project/123/Task http://server/Project/123/Document

I am using mvc1 so I have no access to areas etc. The project section will have a separate master page for project controllers such as task, document etc with a dfferent menu navigaton. I have tried three routes together n Global.asax like:

        routes.MapRoute(
            "Task",
            "Project/{id}/Task/{action}",
            new { controller = "Task", action = "Index", id = "" }
        );

        routes.MapRoute(
            "Message",
            "Project/{id}/Message/{action}",
            new { controller = "Message", action = "Index", id = "" }
        );

        routes.MapRoute(
            "Document",
            "Project/{id}/Document/{action}",
            new { controller = "Document", action = "Index", id = "" }
        );

What am I doing wrong here
