1. What is a socket? What is WebSocket?What's the difference between the two people who have heard about WebSocket technology for the 1th time? WebSocket is the implementation of just porting the socket concept to the browser?We know that two applications (processes) in the network need to communicate with each other at full duplex (that is, both sides can send m

Introduction and principle of websocket WebSocket protocol is a new protocol for HTML5. It implements browser-to-server full-duplex communication (Full-duplex). The first handshake needs to be done with an HTTP request. --Baidu Encyclopedia Purpose: Instant messaging instead of pollingThe Instant Messenger on the website is very common, such as the QQ of the webpage, chat system and so on.

Concept As a next-generation Web Standard, HTML5 has a number of compelling new features, such as canvas, local storage, multimedia programming interfaces, WebSocket, and so on. Today we'll take a look at the WebSocket, which is called "Web TCP." The emergence of WebSocket is based on the real-time needs of Web applications. This kind of real-time web application
