jquery - Long polling issue with IE8 -

im building app uses long polling technique , im running trouble ie8.

so here simplified code use:

php:

 $time = time();     while((time() - $time) < 10) {         $data = rand(0,10);             // if have new data return         if($data == 3 || $data == 6) {             echo json_encode($data);             break;         }             sleep(1);         } 

js:

var lponcomplete = function(response) {         alert(response);         // more processing         lpstart();     };      var lpstart = function() {         $.post('http://example.com/test', {}, lponcomplete, 'json');     };      $(document).ready(lpstart); 

the problems seems ie8 not waiting til server responds fires next request straight after or dies after first proper response. may cause behavior?

this seemed trick.

$.ajaxsetup ({    cache: false });
