title: Should Google Analytics event tracking fire an XHR request?
body: <p>I'm trying to set up <a href="http://code.google.com/apis/analytics/docs/tracking/eventTrackerGuide.html" rel="nofollow">Google Analytics event tracking</a>. This is my code: </p>
  
  <pre><code>var uid = getUUID();
  function postGA() { 
      var sliderval = $("#slider-stock").slider("value");  
      _gaq.push('_trackEvent', uid, sliderval); 
  }
  </code></pre>
  
  <p>I'm noticing that when <code>postGA()</code> is fired, Firebug does not log an XHR request. </p>
  
  <p>Is this normal, or should I expect to see one? If the latter, is there something obviously wrong with my code?</p>
