title: Long Running Wicket Ajax Request
body: <p>I occasionally have some long running AJAX requests in my Wicket application.  When this occurs the application is largely unusable as subsequent AJAX requests are queued up to process synchronously after the current request.  I would like the request to terminate after a period of time regardless of whether or not a response has been returned (I have a user requirement that if this occurs we should present the user an error message and continue).  This presents two questions:</p>
  
  <ol>
  <li>Is there any way to specify a
  timeout that's specific to an AJAX
  or all AJAX request(s)?</li>
  <li>If not, is there any way to kill the current request?</li>
  </ol>
  
  <p>I've looked through the wicket-ajax.js file and I don't see any mention of a request timeout whatsoever.</p>
  
  <p>I've even gone so far as to try re-loading the page after some timeout on the client side, but unfortunately the server is still busy processing the original AJAX request and does not return until the AJAX request has finished processing.</p>
  
  <p>Thanks!</p>
