title: Not Waiting for Response from an AJAX Request
body: <p>Suppose I make an AJAX HTTP Request from jQuery to a backend PHP script. The request is made, the PHP script starts running and doing its magic. Suppose I then change to another website, away from the site where the original AJAX Request was made. As well, I do this before the PHP script finishes and has time to do a HTTP Response back. Does the PHP script finish running and doing its thing even though I've switched to another website before I got the HTTP Response?</p>
  
  <p>So the order is this.</p>
  
  <ul>
  <li>I'm on website www.xyz.com</li>
  <li>I have a jQuery handler that kicks off an AJAX request to blah.php</li>
  <li>blah.php starts running</li>
  <li>I go to website www.abc.com soon after without waiting for a response from blah.php</li>
  </ul>
  
  <p>What's going on with blah.php? Is execution still going on? Did it stop? I mean it didn't get a chance to respond so...</p>
