title: facebook error code 102
body: <p>i have developed a php based app for facebook. now i need to push data into the user's stream.
  for that I have to implement the xd_receiver.html cross domain communication channel. 
  now the problem i am facing is i have done exactly as mentioned in the documentation, but in the console log, I am getting <code>Error Code 102</code>
  It says: </p>
  
  <pre><code>API failed with error code = 102
  Bad session key, clear it
  </code></pre>
  
  <p>It however successfully pulls information like uid and name successfully.</p>
  
  <p>If there is any other way for me to easily push status / feed updates, please let me know.</p>
