User must use GET and POST to establish two channels for downstream and upstream. The
x-sessioncookie in GET and POST should be the same to be recognized as a pair for one session. The
contents of upstream should be base64 encoded to be able to pass through the proxy server.
This channel will help perform real-time event subscription and notification as well as camera
control more efficiently. The event and control formats are described in another document.
See Event/control tunnel spec for detail information
