title: Colorbox content not updating in IE8
body: <p>I am using Colorbox for a date popup and people have been saying to me that the content is not changing (I am using Chrome/FF on a Mac so no IE). Once I looked at it in IE8 I noticed that as soon as I change the value in a database and the windows content changes, IE8 does not show it. I do not have this problem in FF or Chrome. </p>
  
  <p>Here is the content (generated by a PHP script):</p>
  
  <pre><code>&lt;link rel="stylesheet" href="http://mouseware.net/weekendcamping/includes/popupbox/colorbox.css" /&gt;
      &lt;script src="http://mouseware.net/weekendcamping/includes/popupbox/jquery.colorbox-min.js"&gt;&lt;/script&gt;
      &lt;script&gt;
          $(document).ready(function(){
              // Colorbox elements
              $(".inline").colorbox({inline:true, width:"50%", height:"50%"});$(".ajax").colorbox({width:"50%", height:"50%"});$(".ajax_lg").colorbox({width:"75%", height:"75%"});$(".ajax_tall").colorbox({width:"50%", height:"75%"});
          });
      &lt;/script&gt;

  <p>It is being called from the mail file by</p>
  
  <pre><code>$.colorbox({href:'popupDate.php', width:'50%', height:'50%'})
  </code></pre>
  
  <p>My best guess is the popup windows is being cached in IE so it doesn't regenerate the content... but I am not sure. </p>
  
  <p>I have updated the colorbox to the latest, 1.4.15, and jQuery to the latest, 1.9.1. Neither of these updates made a difference. I have also tried putting the content inside the  tags and  tags and that did not help. I also tried adding the no-cache HTML and PHP code to both my parent and the popup box... did not work either. </p>
