redirect to controller from global.asax when session End MVC

Question

Here is my code in global.asax:

protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
        AuthConfig.RegisterAuth();
    }

    //void Session_OnEnd()
    //{
    //    RouteData routeData = new RouteData();
    //    routeData.Values.Add("controller", "Home");
    //    routeData.Values.Add("action", "logout");
    //    //routeData.Values.Add("Summary", "Error");
    //    //routeData.Values.Add("Description", ex.Message);
    //    IController controller = new HomeController();
    //    controller.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
    //}

    //protected void Session_Start(object src, EventArgs e)
    //{
    //    if (Context.Session != null)
    //    {
    //        if (Context.Session.IsNewSession)
    //        {
    //            string sCookieHeader = Request.Headers["Cookie"];
    //            if ((null != sCookieHeader) && (sCookieHeader.IndexOf("ASP.NET_SessionId") >= 0))
    //            {
    //                // how to simulate it ???
    //                // RedirectToAction(“ActionName”, “ControllerName”,  route values);
    //                Response.Redirect("/Home/logout");
    //            }
    //        }
    //    }
    //}

    void Session_OnEnd(object sender, EventArgs e)
    {
        //if (Session.IsNewSession)
        //Response.RedirectToRoute("logout", "Home");

        //RouteData routeData = new RouteData();
        //routeData.Values.Add("controller", "Home");
        //routeData.Values.Add("action", "logout");
        ////routeData.Values.Add("Summary", "Error");
        ////routeData.Values.Add("Description", ex.Message);
        //IController controller = new HomeController();
        //controller.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));

        // HttpContext.Current.RewritePath("Home/logout");
        //Response.Redirect("~/Home/logout");

        //HttpContext.Current.Response.Redirect("~/Home/logout");

    }
