如何在AJAX调用后会话过期时将用户重定向到登录页面

Question

我有以下代码在大多数情况下都能正常工作。

但是当会话过期并且用户执行一些AJAX调用时，它无法正常工作，因此它会返回AJAX错误。

如何以正确的方式管理它？

谢谢！

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = false)]
    public class SessionExpireFilterAttribute : ActionFilterAttribute
    {
        public static String LoginUrl { get; set; }
        public delegate bool CheckSessionDelegate(HttpSessionStateBase session);

        public static CheckSessionDelegate CheckSessionAlive;

        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {

            HttpSessionStateBase session = filterContext.HttpContext.Session;
            if ((CheckSessionAlive == null) || (CheckSessionAlive(session)))
                return;


            //send them off to the login page
            var url = new UrlHelper(filterContext.RequestContext);
            var loginUrl = url.Content(LoginUrl);
            session.RemoveAll();
            session.Clear();
            session.Abandon();

            filterContext.HttpContext.Response.StatusCode = 403;
            filterContext.HttpContext.Response.Redirect(loginUrl, false);
            filterContext.Result = new EmptyResult();

        }
}

我目前的解决方案如下，但这是正确的吗？

function UpdateSelectedProduct(uid, checked) {
      $lastProductUID = uid;
        var params = { uid: uid, isSelected: checked };
        $.ajax({
            type: "POST",
            url: '@Url.Action("UpdateSelectedProduct", "Orders")',
            data: JSON.stringify(params),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (data) {

            },
            error: function () {
                // alert("Timeout error.");
                document.location.href = "/";  // <---- Here it is
            }
        });
    }
