You can use the session items in Application_BeginRequest this way:

    protected void Application_BeginRequest(object sender, EventArgs e)
    {
        //Note everything hardcoded, for simplicity!
        HttpCookie cookie = HttpContext.Current.Request.Cookies.Get("LanguagePref");

        if (cookie == null)
            return;
        string language = cookie["LanguagePref"];

        if (language.Length<2)
            return;
        language = language.Substring(0, 2).ToLower();   
        HttpContext.Current.Items["__SessionLang"] = language;
        Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(language);

    }

    protected void Application_AcquireRequestState(object sender, EventArgs e)
    {
        HttpContext context = HttpContext.Current;
        if (context != null && context.Session != null)
        {
            context.Session["Lang"] = HttpContext.Current.Items["__SessionLang"];
        }
    }
