        {
            if (!filterContext.ActionDescriptor.IsDefined(typeof(AllowAnonymousAttribute), true) && !filterContext.ActionDescriptor.ControllerDescriptor.IsDefined(typeof(AllowAnonymousAttribute), true))
            {
                if (UserHelper.CurrentUser == null)
                {
                    filterContext.Result = new RedirectResult(string.Format("/OAuth2/IndexUserInfo?returnUrl={0}", filterContext.HttpContext.Request.RawUrl));
