Problem switching culture

Question

i have 2 links for switching culture. if i click one link, the program call a method with this code:

        Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo(ln);
        Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(ln);
        return RedirectToAction("index");

If i look with debug the culture is correctly changed, but in the Index redirection, the cultureUI is not changed.

I'm trying locally with visual studio web server(Cassini).

thank you

We do the same thing from links on the view. However we do not put the code in action but rather a method on a base controller class. This is the action:

public ActionResult SetCulture(string cultureCode)
    {
        string returnUrl = string.Empty;
        if (Request != null)
        {
            returnUrl = Request.UrlReferrer.ToString();
            //Write to the cookie
            Response.Cookies.Add(new HttpCookie("Language", cultureCode));
        }

        if (!String.IsNullOrEmpty(returnUrl))
        {
            return this.Redirect(returnUrl);
        }
        else
        {
            return RedirectToAction("List");
        }
    }

And this is the method in the base Controller class:

 protected override void ExecuteCore()
    {
        //Retrieve from cookies
        HttpCookie cultureCookie = Request.Cookies["Language"];
        if (cultureCookie != null)
        {
            string culture = cultureCookie.Value;
            if (!String.IsNullOrEmpty(culture))
            {
                Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(culture);
                Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo(culture);
            }
        }
        base.ExecuteCore();
    }

Answer 2

I've resolved symply adding this method in the global.asax:

   void Application_PostAcquireRequestState(object sender, EventArgs e)
 {
   Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(languageFromSession);
   Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(languageFromSession);
}

This method is called everytime i call an action in a controller.

In this way i don't use cookies and I do not need to inherit any controller from a base controller.

I think it is the better solution.
