title: Facebook Referral URL decode
body: <p>Sometimes I get burst of visitors from Facebook, which I am curious to know where exactly on Facebook if the page is public, of course!</p>
  
  <p>Is there a way to decode and track back Facebook referral URL to actual page in the Facebook?</p>
  
  <p>URL format is the following:<br>
  <a href="http://www.facebook.com/l.php?u=http%3A%2F%2Fwww.domain.com%2F&amp;h=iAQDjUC4AQHjQeIXcOi8z9jamgyDk8vpuylpdaRT3aHu6Q&amp;s=1" rel="nofollow">http://www.facebook.com/l.php?u=http%3A%2F%2Fwww.domain.com%2F&amp;h=iAQDjUC4AQHjQeIXcOi8z9jamgyDk8vpuylpdaRT3aHu6Q&amp;s=1</a></p>
  
  <p>From mobile it is shorter:<br>
  <a href="http://m.facebook.com/l.php?u=http%3A%2F%2Fwww.domain.com%2F&amp;h=BAQFX067m&amp;s=1" rel="nofollow">http://m.facebook.com/l.php?u=http%3A%2F%2Fwww.domain.com%2F&amp;h=BAQFX067m&amp;s=1</a></p>
  
  <p>Where <code>domain.com</code> is my website for example.</p>
