Question

I have got following routing, which basically enables me to keep the language within the url and makes sure only de and fr (constraint) is possible. In the Default – Routing, I set de as standard if there is no language in the url contained:

// Routing with language
routes.MapRoute("Default_with_language", "{lang}/{controller}/{action}/{id}", new
{
    controller = "Home",
    action = "Index",
    id = UrlParameter.Optional,
}, new { lang = "de|fr" });
// Standard-Routing
routes.MapRoute("Default", "{controller}/{action}/{id}", new
{
    controller = "Home",
    action = "Index",
    id = UrlParameter.Optional,
    lang = "de",
});

How can I change the default-language in each request? Let’s say I have two Urls, one in german and one in french, I would like to have lang = "fr" if the french url is called…

Thx for any tipp

In your Application_BeginRequest handler, you can access the current route and you should be able to change the values using something like this.

 HttpContext.Current.Request.RequestContext.RouteData.Values.Add("lang", detectedLanguageFromUrl);

Hopefully, that’s enough to make routing pick up the new value.
