title: How to get full url of referring links
body: <p>Assume there a page containing a link to my site and the url for this referring page was this:</p>
  
  <p><a href="http://source.com/referral_path/topic.php?t=123" rel="nofollow">http://source.com/referral_path/topic.php?t=123</a></p>
  
  <p>In google analytics it would display as this:</p>
  
  <ul>
  <li><strong>ga:source</strong>: source.com</li>
  <li><strong>ga:referral_path</strong>: /referral_path/topic.php</li>
  </ul>
  
  <p>I recall long ago there was a switch/setting which would control whether the <strong>t=123</strong> (i.e. query parameters) would be included as part of the referral_path or not.  Is this correct?  And if it is how do I control it.</p>
