title: Facebook Deauthorize CallBack Url not being pinged
body: <p>I'm running a facebook app on localhost using wamp. My application is working fine on localhost. 
  I've specified the deauthorize callback url in the app settings as </p>
  
  <p>"http://localhost/MyApp/deauthorize.php"</p>
  
  <p>But when I remove the app, deauthorize.php is not being pinged. I'm able to access this script over my machine. 
  I tried <a href="http://developers.facebook.com/tools/debug" rel="nofollow">http://developers.facebook.com/tools/debug</a> tool, but i gets error in parsing localhost URLs.
  Is it that I can't give localhost url to deauthorize? or if I m missing something. 
  Any help is appreciated.
  Thank You</p>
