How to manage a redirect request after a jQuery Ajax call

0 votes

I'm using $.post() to call a servlet using Ajax and then using the resulting HTML fragment to replace a div element in the user's current page. However, if the session times out, the server sends a redirect directive to send the user to the login page. 

In this case, jQuery is replacing the div element with the contents of the login page, forcing the user's eyes to witness a rare scene indeed.

How can I manage a redirect directive from an Ajax call with jQuery?

Hii,

You can solved this issue by:

  1. Adding a custom header to the response:

    public ActionResult Index(){
        if (!HttpContext.User.Identity.IsAuthenticated)
        {
            HttpContext.Response.AddHeader("REQUIRES_AUTH","1");
        }
        return View();
    }
  2. Binding a JavaScript function to the ajaxSuccess event and checking to see if the header exists:

    $(document).ajaxSuccess(function(event, request, settings) {
        if (request.getResponseHeader('REQUIRES_AUTH') === '1') {
           window.location = '/';
        }
    });

Hope it is helpful!!
