Why ajax call's timeout not working properly

In my ASPX page I call a javascript function which contains an Ajax call with 5 seconds timeout.

I first try to call this function with internet connection off and timeout works properly. But when I call this function for the second time, Ajax call directly calls success function, without waiting for timeout and subsequent error function.

Here is the the ajax call

$.ajax({
     type: "POST",
     url: pageUrl + "/SubmitAnsGetNewQue",
     data: jsonParamsForSbmt,
     timeout: 5000,
     contentType: "application/json; charset=utf-8",
     dataType: "json",
     async: true,
     success: SetNextQueSet,
     error: OnErrorCall
});

timeout isn't what you think in this context, it's the amount of time in miliseconds that jQuery will wait for the ajax request to return.

If it took more than 5 seconds to the server to reply, the callbacks won't fire.

timeout

Set a timeout (in milliseconds) for the request. This will override any global timeout set with $.ajaxSetup(). The timeout period starts at the point the $.ajax call is made; if several other requests are in progress and the browser has no connections available, it is possible for a request to time out before it can be sent. In jQuery 1.4.x and below, the XMLHttpRequest object will be in an invalid state if the request times out; accessing any object members may throw an exception. In Firefox 3.0+ only, script and JSONP requests cannot be cancelled by a timeout; the script will run even if it arrives after the timeout period.
