title: Getting URL from a child iframe
body: <p>Is it 100% impossible to get the browser URL from the iframe html of an iframe that is loaded onto a separate domain? I tried javascript and it did not work. What language could I do this in? Thanks!</p>
  
  <p>UPDATE
  Thanks for the help! PHP does work.</p>
  
  <pre><code>&lt;?php 
  if(isset($_SERVER['HTTP_REFERER'])) 
  {
      echo $_SERVER['HTTP_REFERER'];
  }?&gt;
  </code></pre>
