title: Javascript popup window detect page loads?
body: <p>Lets say I have a javascript popup window (opened using <code>var popup = window.open()</code>), that is pointing to the same domain.</p>
  
  <p>How can I detect each time a page is loaded from the page that opened the popup (eg. after a link is clicked on or a form is submitted) o I can check if the user performed an action? Bonus points if I can get the url and response code for the page (that is loaded in the popup).</p>
  
  <p>I'd also like to note I would <strong>not</strong> like to rely on the loaded page within the popup to provide information (by firing events).</p>
