title: Progress bar and jquery ajax
body: <p>There is a way to get a progress bar that interfaces with a jquery ajax?
  I ask this because i followed this <a href="http://net.tutsplus.com/tutorials/javascript-ajax/uploading-files-with-ajax/" rel="nofollow">tutorial</a> to build an ajax upload with jquery, and it would be useful to see the progress of the upload.</p>
  
  <p>Thanks.</p>
