[s2; Provides the WebSocket protocol support. WebSocket is a wrapper 
over existing TcpSocket connection, which performs server handshake 
by calling WebAccept method.&]

to client `- Recieve does not return and waits for the next message, 
CLOSE is replied by CLOSE and Recieve returns. Returns the content 
of message recieved or String`::GetVoid() if there was none. Note: 
If WaitRead was used to wait for read on socket before calling 
Recieve, returning String`::GetVoid() means that connection was 
broken.&]
