title: Simple AJAX/jQuery application to show files in real time during copy
body: <p>While studying Ajax/jQuery, I am trying to setup this test environment:</p>
  
  <ol>
  <li>the server recursively copy a full folder form one location to
  another; </li>
  <li>the client should display the list of copied files, one
  by one, in real time until the copy ends;</li>
  <li>in the client thereshould be a button to abort the copy operation.</li>
  </ol>
  
  <p>Can you pls point me to a simple skeleton of this problem, or give me any clue?
  Thanks, I appreciate.</p>
