title: Correct usage of Appengine Sockets
body: <p>I'm using the sockets api to communicate with the Apple Push Notification Service, although I'm not confident I'm using it correctly...</p>
  
  <p>I have an initialization function where I establish my connection to APNS. However when is the correct time to call Close() on the connection? Or do I just leave it open and keep reusing it?</p>
  
  <p>Thanks!</p>
