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 a proxy server.

This channel will help to transfer the raw data of UART over the network.

Please see UART tunnel spec for detail information
