title: How to get original referrer url when invoking javascript??
body: <p>Let us take i am in site named <code>domain1.com</code> and navigating to another site <code>domain2.com</code>, where i invoke a external js call.</p>
  
  <p>The problem is the referrer of the js call is <code>domain2.com</code> and but i need the original referrer i.e. <code>domain1.com</code>. I see that the google analytics request, i see that the query parameter utmr hold the referrer url. example - <a href="http://www.google.com/url?sa=t&amp;source=web&amp;cd=1&amp;sqi=2&amp;ved=0CCkQFjAA&amp;url=https://stackoverflow.com/&amp;rct=j&amp;q=stack%20overflow&amp;ei=h0XETcL2IJOisQOCjeWXAQ&amp;usg=AFQjCNERidL9Hb6OvGW93_Y6MRj3aTdMVA&amp;sig2=FSy1Krjsn8B9Njr0Pz3YxA" rel="nofollow noreferrer">utmr</a>    </p>
  
  <p>Any idea how to get the same as that in GA ?</p>
