php - jQuery $.ajax POST Request with IE 9 results empty array -

i have problem coding, in firefox works fine in ie9 works first ~5 seconds. after time don't receive post data anymore.

i want load php page via ajax using values of form inputs post variables. first 5 seconds can receive post on requested page after receive empty string.

here code:

function reload_form(){ var data = $("#formularfelder").serialize()     $.ajax({         type: 'post',         url: 'content/formular.php',         data: data,         success: function(msg) {              $("#form_container").html(msg);         }     }); } 

is bug of ie9 , there workaround available?

it awesome if me! :)

******edit****

i found reason issue @ post:

why internet explorer not send http post body on ajax call after failure?

ie runs keep-alive timout , doesn't send body within post data anymore.

to workaround problem send packet in regular time intervalls (equal keep-alive timeout) server keep keep-alive. cause little bit traffic (~200 bytes per refresh) it's still more practicable workaround disabling keep-alive in apache.

this solution found problem

for same problem here's refreshing code keep-alive timeout of 5 seconds:

var updatediv = function () {     $.ajax({type: 'post', url: 'timeout.php'});     yourtimer = window.settimeout(updatediv, 5000); }  $( document ).ready(function() {     var yourtimer = window.settimeout(updatediv, 5000); }); 

1. please change jquery version. faced same problem in ie9 when use jquery.js version 1.10. when try version 1.8 problem solved.

or

2. you can add line in code $.support.cors = true;

or

3.you can add jquery migrate js file resolve this. http://code.jquery.com/jquery-migrate-1.2.1.js
