title: jQuery and AJAX response header
body: <p>So I've got this jQuery AJAX call, and the response comes from the server in the form of a 302 redirect. I'd like to take this redirect and load it in an iframe, but when I try to view the header info with a javascript alert, it comes up null, even though firebug sees it correctly.</p>
  
  <p>Here's the code, if it'll help:</p>
  
  <pre><code>$j.ajax({
      type: 'POST',
      url:'url.do',
      data: formData,
      complete: function(resp){
          alert(resp.getAllResponseHeaders());
      }
  });
  </code></pre>
  
  <p>I don't really have access to the server-side stuff in order to move the URL to the response body, which I know would be the easiest solution, so any help with the parsing of the header would be fantastic. </p>
