Why is the url not routable?

Question

ASP.NET

Hello!
in asp.net mvc3 application add route:

routes.MapRoute(
                "SP",
                "SP/{controller}/{action}/{id}",new { controller = "SPHome", action = "Index", id = UrlParameter.Optional },
                new { controller = @"OrgBill|OrgInfo|SPHome" });

question: why does this route not send a request to localhost :12345/sp/ to the SPHome controller, Index method?
Thank you for your attention.

Answer 1

Most likely added in the wrong place, but I could be wrong. Add this route before the default one.

Answer 2

Maybe the controller class is called SPHome instead of SPHomeController?
