simple websocket

a · What is WebSocketThe WebSocket protocol can communicate more than once after a successful handshake from the HTTP protocol until the connection is closed. However, the handshake in WebSocket is compatible with the handshake in HTTP, which uses the Upgrade protocol header in HTTP to upgrade the connection from HTTP to WebSocket. This makes it easier for the

programming implementation, but also increases the server-side load, restricting the scalability of the application system.HTML5 WebSocket designed to replace polling and Comet technology, so that the client browser has a desktop system like the C/s architecture of real-time communication capabilities. The browser sends a request to the server to establish a WebSocket connection through JavaScript, and aft

------------------------------------------- Continue to say that WebSocket can see some things from w3c, such Content sent from the client to the server: 1. GET/chat HTTP/1.12. Host: server.example.com3. Upgrade: websocket4. Connection: Upgrade5. Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ =6. Origin: http://example.com7. Sec-WebSocket-Protocol: chat, superchat8.

Because the HTTP protocol is stateless, building a chat room like this has never felt gegedada is not so logical. If you do not use the flash, applets and other browser plug-ins, we need to periodically poll the server to get everyone's chat information. This creates a certain amount of latency and a lot of network traffic

as:Ws://example.com/chatwss://example.com/chatBy default, the WS protocol for Websocket uses port 80, and the WSS protocol uses 443 ports by default when running over TLS. In fact, WSS is the WS SSL-based secure transmission, and HTTPS as the same kind of truth.If your site is HTTPS protocol, then you can not use, the ws:// browser will block off the connection, and HTTPS does not allow the same HTTP request, such as:650) this.width=650; "Src=" http:
