When registering this, you will need to do it in the Bootstrapper.Bootstrapped event. This ensures that it is registered AFTER Feather register's its MvcPageRouteHandler. For instance:

Global.asax.cs

        protected void Application_Start(object sender, EventArgs e)
        {
            Bootstrapper.Bootstrapped += Bootstrapper_Bootstrapped;
        }

        void Bootstrapper_Bootstrapped(object sender, EventArgs e)
        {
                CustomPageRouteHandler.RegisterType();
        }

Hi, is this the route handler (MvcPageRouteHandler) for MVC feather widgets only, or MVC pages? Can't seem to get the OutputCache attr to work in my widget controller action methods [OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")], and was wondering if this would be a workaround.
