Ok I see what you're tryign to do. Well, if you want different URLs for each language/culture then you need to do this at the routing level. But if all you want is to know which language the user wants and then render different makrup, then you could implement a HttpModule to set the culture. In other words, the HttpModule approach doesn't need to have different URLs for each culture -- you can determine the culture either form a HTTP header (Accept-Language) or if the user is logged in then maybe some setting in the database.
