title: uses XmlHttpRequest asynchronously for server requests, how many maximum simultaneous requests would be possible
body: <pre><code>function startAR()
  {
  for (var a = 0; a &lt; 100; a++){
  executeAR();
  }
  };
  </code></pre>
  
  <p>And considering that executeAR() uses XmlHttpRequest asynchronously for server requests, how many
  maximum simultaneous requests would be possible in this cycle?</p>
