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

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

In my web.config I set:

<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:

$(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)

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?

Thanks guys for the help!

I just forgot to add to my web.config:

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

Now I get 401 as expected!
