title: Logging out from Facebook with access_token, but active sessions remain
body: <p>I am using the <code>Facebook API</code> in a <code>C++</code> application with <code>libcurl</code>.
  Logging in works good, I can retrieve some user information after the user has registered my application. 
  The problem is, when I want to log the user out via </p>
  
  <p><code>https://www.facebook.com/logout.php?access_token=RETRIEVED_TOKEN&amp;confirm=1&amp;next=http://www.google.com</code> ,
  there are still remaining active sessions in my account settings (security).</p>
  
  <p>I don't want these sessions to remain as the logout should clean these.
  How can I smoothly clean those active sessions when logging out?
  Do I have to add the <code>APP_ID</code> to the URL?</p>
