WebSocket relay server
Creates communication channels between web clients
Description
Allows multiple clients, usually web clients or devices beihind NAT with no
direct connectivity with each other to exchange messages. Supported protocols:
RAW TCP, TLS, WebSocket and secure WebSocket. Secure connections require a
certificate file in the current directory with the name gvalkov.com.pem.
The server automatically uses the protocol requested by the client, and falls
back to RAW if no protocol is detected. Port 81 is used by default, see
G_SOCKET::config in g_socket.cpp.
Cube3D_devicemotion can be
used as a sample client, where one device shares its accelerometer data with
another. Browsers should display rotating cube.
