How can my route use optional parameters in the middle of the URL using ASP MVC3?

Question

I would like my URLs to use the convention:

/{controller}/{id}/{action}

rather than

/{controller}/{action}/{id}

I think you probably need two separate routes for this.

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

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