Websocket Server Broadcast

A WebSocket server is a TCP application listening on any port of a server that follows a specific protocol, simple as that. The server side code which receives this call looks like the following:. RFC 6455, the WebSocket protocol defines the capability for the web applications to be two-way, full-duplex between client and server for communication. OK, I Understand. The server can push new information to the client whenever it deems it necessary and the client can do the same to the server. This tutorial shows how to create a web application that uses ASP.
