title: Extjs two ajax request blocking problem
body: <p>I have a problem with ajax requests. I need them to go independently not blocking each other. </p>
  
  <p>The situation looks like this.
  I have first ajax request which takes about 1minute and multiple other requests which are almost instantaneous. The 1minute request blocks other requests from happening. I need a way around.</p>
  
  <p>Edit:<br />
  Well I get a hanging process in firebug which normally ends in 200ms. The other problem is if I abort the request it still takes same time as if I didn't aborted. A bug or am I aborting it in a wrong manner?</p>
  
  <p>Base concept is like this:</p>
  
  <ol>
  <li>load a store with onload event which has Ajax request to 60s script</li>
  <li>I click a button that triggers another Ajax request to 200ms script</li>
  <li>the second request waits for the first to end and then ends</li>
  </ol>
  
  <p>I tried a different aproach also:</p>
  
  <ol>
  <li>load a store with onload event which has Ajax request to 60s script</li>
  <li>I click a button that triggers another Ajax request to 200ms script</li>
  <li>abort first Ajax request
  <ul>
  <li>as expected firebug shows the request was aborted</li>
  <li>the second script still takes 60s+200ms to end</li>
  </ul></li>
  </ol>
  
  <p>Any ideas?</p>
