title: jQuery $.getJSON not sending request in IE (works in FF and Chrome)
body: <p>I am in IE9's debug mode. I put a breakpoint on the first line (below), and it hits. However, my breakpoint on the first line in the callback is never hit.</p>
  
  <p>After looking in the <strong>Network</strong> tab, I don't see a request to the URL (set to <code>"http://localhost/PopNote/"</code>).</p>
  
  <pre><code>$.getJSON(
              URL + "messages/getUnreadMessages.json?" + Math.random(), // add random to prevent IE cache
              {
                  productKey      : this.productKey,
                  listIds         : this.listIds,
                  personEmail     : this.personEmail
              },
              function(data) {    
                  if(data.messages.length == 0) return;
  </code></pre>
  
  <p>Why is the request not being sent (and only in IE)?</p>
  
  <p>Thanks!</p>
