I want this: http://mystore.somewhere/my-category-1/ So far I've been able to solve it by using: routes.MapRoute( "Category", "{alias}/{pageNumber}", new { controller = "Categories", action = "Browse", pageNumber = 1 }); But this catches way too much than just what I'd like. After reading through some questions and answers around this site, I
