如何检查ajax调用会话是否过期？

I am using asp.net and I have $.ajax calls in my web application for every request to the server.

我正在使用asp.net,我在我的Web应用程序中为服务器的每个请求都有$ .ajax调用。

I want to redirect the user to the Login page on session end.

我想将用户重定向到会话结束时的登录页面。

In my web.config I set:

在我的web.config中我设置:

<authentication mode="Forms">
  <forms name=".CovertixAuthenticated" defaultUrl="Default.aspx" loginUrl="LoginPage.aspx" slidingExpiration="true" cookieless="UseCookies" protection="All" timeout="1"/>
</authentication>


  <sessionState mode="InProc" cookieless="UseCookies" timeout="1"/>

and I check in .ajaxError:

我签入.ajaxError:

$(document).ajaxError(function(xhr, props) {
    if (props.status == 401) {
        var ParentUrl = encodeURIComponent(window.parent.location.href);
        //alert(getLoginPage());
        document.location.href = getLoginPage() + "?ReturnUrl=" + ParentUrl;
    }
});

The problem is I get responseCode = 500 (Internal server error)

问题是我得到responseCode = 500(内部服务器错误)

What is the best way to check if session expired on ajax call, or how can I redirect the user to the login page automatically when session ends?

检查会话是否在ajax调用上过期的最佳方法是什么,或者如何在会话结束时自动将用户重定向到登录页面?

Thanks guys for the help!

谢谢大家的帮助!

I just forgot to add to my web.config:

我只是忘了添加到我的web.config:

  <location path="MyPage.aspx">
    <system.web>
      <authorization>
        <deny users="?"/>
      </authorization>
    </system.web>
  </location>

Now I get 401 as expected!

现在我按预期得到了401!
