ASP.net MVC3 Multilingual Route Rewriting

Question

Is there any good method to create route rewriting for a multilingual web application?

---

The URL schema should be the following

http://<Domainname>/{Language}/{Controller}/{Action}/{Id}

but URLs without the Language part should also be supported, but they should not just map to the controllers directly but generate a redirect response.

The important thing here is that the redirect should not be hard coded to a specific language but be determined based on factors like the users preferred language if possible.

Note: The process of determining the correct language is not the problem, just how to do the non static rewriting.

Thanks

I managed that with following routes;

    routes.MapRoute(
            "Default", // Route name
            "{language}/{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", language = "tr", id = UrlParameter.Optional }, // Parameter defaults
            new { language = @"(tr)|(en)" }
        );

I handle the culture by overriding the GetControllerInstance() method of DefaultControllerFactory. the example is below;

public class NinjectControllerFactory : DefaultControllerFactory {

protected override IController GetControllerInstance(System.Web.Routing.RequestContext requestContext, Type controllerType) {

    //Get the {language} parameter in the RouteData

    string UILanguage;

    if (requestContext.RouteData.Values["language"] == null) {

        UILanguage = "tr";
    }
    else {

        UILanguage = requestContext.RouteData.Values["language"].ToString();
    }

    //Get the culture info of the language code
    CultureInfo culture = CultureInfo.CreateSpecificCulture(UILanguage);
    Thread.CurrentThread.CurrentCulture = culture;
    Thread.CurrentThread.CurrentUICulture = culture;

    return base.GetControllerInstance(requestContext, controllerType);
}

}

and register it on the global.asax;

protected void Application_Start() {

    //other things here


    ControllerBuilder.Current.SetControllerFactory(new NinjectControllerFactory());
}
