Here is the custom route code:

public class CustomRoutingEventHandler : ApplicationEventHandler
{
    protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        var product = RouteTable.Routes.MapUmbracoRoute(
            "Product",
            "catalog/{x}/{y}",
            new { controller = "product", action = "index" },
            new CustomRouteNodeRouteHandler("product"));
    }
}

public class CustomRouteNodeRouteHandler : UmbracoVirtualNodeRouteHandler
{
    private string _documentTypeAlias;

    public CustomRouteNodeRouteHandler(string documentTypeAlias)
    {
        _documentTypeAlias = documentTypeAlias;
    }

    protected override IPublishedContent FindContent(RequestContext requestContext, UmbracoContext umbracoContext)
    {
        var helper = new UmbracoHelper(umbracoContext);
        return helper.TypedContentAtRoot()
            .First()
            .Descendants()
            .First(d => d.DocumentTypeAlias.InvariantEquals(_documentTypeAlias));
    }
}

This associates the route catalog/{x}/{y} with my "Product" document type. Here is the controller for that page:

public class ProductController : RenderMvcController
{
    public ActionResult Index(RenderModel renderModel, string x, string y)
    {
        var model = new ProductModel(renderModel.Content);
        return View("Product", model);
    }
}

Hi Megan,

What I would do in this case is setup a second action, for example product and use that for the virtual route.

Than in the index method I would return a 404 or redirect to the parent.
