title: Strange Ajax / Jquery behaviour in Internet Explorer 9
body: <p>I have an ajax call inside a javascript function that update a div with the result. This function is called every 2 seconds. </p>
  
  <pre><code>function RefreshNbrMsg() { 
     $.ajax({ 
        url: 'helper/NewMessages.aspx', 
        success: function (data) { 
           $('#nbr_msg').empty().append(data); 
        } 
     }); 
  } 
  
  $(document).ready(function () { 
     setInterval(RefreshNbrMsg, 2000); 
  }); 
  </code></pre>
  
  <p>My problem is that it's working perfectly with Chrome but not IE. In IE the div won't update. </p>
  
  <p>I don't have any script error or messages. I can see in the network analyzer that the ajax call is done every 2 seconds. </p>
  
  <p>/helper/NewMessages.aspx GET 304 text/html 108 B &lt; 1 ms JS Library XMLHttpRequest</p>
  
  <p>Any ideas ? </p>
