Set culture using cookie in asp.net, not updated

Question

I'm using asp.net and want to make it possible for the user to set the culture to use in the website by himself. In MasterPage I have the following code to set a language cookie:

protected void Page_Load(object sender, EventArgs e) {

    if (Request.QueryString["setLanguage"] != null)
    {
        HttpCookie languageCookie = new HttpCookie("language");
        languageCookie.Value = Request.QueryString["setLanguage"];
        languageCookie.Expires = DateTime.Now.AddDays(10);
        Response.SetCookie(languageCookie);
    }
}

In Global.asax I use the cookie like this:

protected void Application_BeginRequest(object sender, EventArgs e) {
    HttpCookie languageCookie = System.Web.HttpContext.Current.Request.Cookies["language"];
    if (languageCookie.Value != null)
    {
        System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(language);
        System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo(language);
    }
}

The problem is that after I set the cookie with Response.SetCookie I need to reload the page to get the new language. How can I make my code so when the user set a new language the page is reloaded with the new language directly?

Answer 1

You can do

Response.Redirect(Request.PathAndQuery);

But why not just set the language after setting the Cookie? You can even use the BeginRequest event to check for specific input being posted and use it as an alternative condition for setting the language.
