Hi there, I'm in the process of upgrading my client's v4.7.2 Umbraco site to v6.0.2.

I'm proceeding along the upgrade paths and I have hit a problem at version 4.10.1.

We have a custom IHttpModule which uses ASP.NET routing to override the Umbraco routing in v4.7.2.  Now that Umbraco supports MVC, the architecture has changed and our custom routes no longer work.  Some of the route are static, like /api, /filters, etc, however, we also have about 150 dynamic routes... i.e., they're read from the database and are essentially redirectors for a very old version of the website.

This is the code for the Register Routes function:

public static void RegisterRoutes()
        {
            var routes = RouteTable.Routes;

            routes.Clear();

            using (var dc = new OrigEntities())
            {
                dc.Redirectors.ToList().ForEach(x =>
                {
                    var name = "dynroute" + x.id;
                    routes.MapHttpHandler<Handlers.Redirector>(name: name, url: x.OldUrl, dataTokens: new { url = x.NewUrl });
                });
            }

            routes.MapHttpRoute(name: "RPCApi",
                routeTemplate: "rpcapi/{action}/{id}",
                defaults: new { id = RouteParameter.Optional, controller = "RPCApi" }
            );

            routes.MapHttpHandler<Handlers.RssFeed>(url: "rss");
            routes.MapHttpHandler<Handlers.XmlFeed>(url: "xml");
            routes.MapHttpHandler<Handlers.XmlFeed>(url: "aspx/rss.aspx"); // old legacy rss url (actually an xml feed)
            routes.MapHttpHandler<Handlers.Triangle>(url: "triangle/{colour}/{dimensions}");
            routes.MapHttpHandler<Handlers.WorldPayReturn>(url: "worldpayreturn");
            routes.MapHttpHandler<Handlers.EventDetail>("EventDetail",
                "events/{type}/{city}/{locality}/{date}/{templateid}/{id}/{page}", new { page = "info" }, null);

            routes.MapPageRoute("filter-page", "filters/{when}/{city}/{locality}/{category}/{venue}/{venueid}", "~/aspx/filters.aspx", false, new RouteValueDictionary(
                new
                {
                    when = "anytime",
                    city = "any-city",
                    locality = "any-locality",
                    category = "any-category",
                    venue = "any-venue",
                    venueid = "any"
                }));
        }

Is it going to be possible to create dynamic routes on the application's start up? I have already integrated this code within the OnApplicationStarted method of an UmbracoApplication instance, but it has no effect for either static or dynamic routes.

thanks for your help
