Client data refresh QWebSocket passive network module (D)

A brief
WebSocket is a Web-based protocol, designed to enable two-way communication between a client application and a remote host. If the initial handshake is successful, the two entities can send data back and forth. WebSocket is to try to get by with less delay and minimum data exchange network application solutions for real-time data.
