Dynamic Ajax Content not refreshing in IE

Dynamic Ajax Content:
http://www.dynamicdrive.com/dynamici...jaxcontent.htm

Ok I have a site that's using Dynamic Ajax Content to reload a php file into a div with a reloading timer. It works in Firefox perfectly, but in IE it does not get new content (doesn't really refresh the php file into the div).

Here's the link to the site:
http://www.albumflip.com/newtest2.php

Here's the code for the newtest2.php:

Code:

<html>
<head>
<title>test</title>
<META name="description" content="test">
<META name="keywords" content="test">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<style type="text/css">
<!--
body {
	background-color: #555555;
	margin-left: 0px;
	margin-top: 0px;
	margin-right: 0px;
	margin-bottom: 0px;
	background-image: url(images/bg2.png);
}
-->
</style>
<link href="newstyle.css" rel="stylesheet" type="text/css">
<style type="text/css">
<!--
A:link {color:#568DB8;text-decoration:none}
A:visited {color:#568DB8;text-decoration:none}
A:hover {color:#888888;text-decoration:none}
body,td,th {
	color: #CCCCCC;
}
.style1 {color: #C987F5}

<script type="text/javascript">
ajaxpage('loadsetlistnew.php', 'setlistajax')
</script>

Here's the code for the loadsetlistnew.php:

Code:

<?php


		 
function countdiff($y, $mo, $d, $h, $m)
{
$cdate = mktime($h, $m, 0, $mo, $d, $y, -1);
$today = time();
$difference = $cdate - $today;
if ($difference < 0) { $difference = 0; }
$dleft = floor($difference/60/60/24);
$hleft = floor(($difference - $dleft*60*60*24)/60/60);
$mleft = floor(($difference - $dleft*60*60*24 - $hleft*60*60)/60);
$countdowndate = date("F j, Y, g:i a",$cdate);
echo "<br><br><b>The next event occurs in <br><font color=\"#6A9BFF\">$dleft days, $hleft hours, and $mleft minutes.</font><br>  <br>This event is scheduled for $countdowndate.</b>";
}	  
 


	  $month = date("m");
	  $day = date("d");
	  $year = date("y");
	  $hourminute = date("Hi");
	  
	  $cdyear = 2006;
	  $cdmonth = 05;
	  $cdday = 30;
	  $cdhour = 19;
	  $cdminute = 00;
	  

if ($month<="05" && $day<="29" && $year=="06")
{if (!$year) { die; }
countdiff($cdyear,$cdmonth,$cdday,$cdhour,$cdminute);}




?>

If you load the link into Internet Explorer, you will see that the statement that says "The next event occurs in
83 days, 2 hours, and 28 minutes." never changes. The minutes should go down every minute.

If you load the link into Firefox, the minutes countdown every minute without ever having to manually refresh the browser which is the way it should work.

Any help would be greatly appreciated.

inside the Ajax JavaScript, find the line:

Code:

page_request.open('GET', url, true)

and change that to:

Code:

page_request.open('GET', url+'?bustcache='+new Date().getTime(), true)

That should bust caching of the fetched file in IE.
