i am using the following route to map to a controller that finds something by a Tag
routes.MapRoute(
            "SearchByTagname",
            url: "Search/Tag/{tagname}",
            defaults: new { controller = "Search", Action="Tag", tagname = "" });
It works fine, if there is no point (.) in URL.
Calling /Search/Tag/ASP.NET gives me 404.
Thank you & regards
Stephan
