WebSocket and websocket 1. What is webSocket? As we all know, the browser supports stateless http. When a user sends a request on the browser side, the server returns a response. This kind of response can be sent only when the user requests continuously. Before html5, to implement a real-time service data retrieval fun
WebSocket connection is closed. If you want to connect to the server asynchronously, useWebSocket.ConnectAsync ()Method. AvailableWebSocket.Send (string),WebSocket.Send (byte[])OrWebSocket.Send (System.IO.FileInfo)Method to send data. If you want to send data asynchronously, useWebSocket.SendAsyncMethod. To explicitly close the connection, useWebSocket.CloseMethod. 2. WebSocket Server using System;using We
connection, and the real-time advantage is obvious.We'll look at the difference between the WebSocket communication and the traditional HTTP via the client-side and service-end messages:On the client side, new WebSocket instantiates a newer WebSocket client object that connects a server like Ws://yourdomain:port/path
As we all know, the HTTP protocol is stateless and interacts with the server based on Request/response, which is what we often call the single-mode. However, with the development of the Internet, the two-way communication between the browser and the server is increasing, and the way of long polling to the servers to get the latest data and push effect is becoming more and more satisfying. HTML5 Standard, also provides us with the browser and the service

comet streaming. Its API is also easy to use, without the need for additional layers to be used directly, while comet requires a good library to handle reconnection, timeouts, Ajax requests, confirmations, and the choice of different transports (Ajax long polling and Jsonp polling).

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
1. What is WebSocket?The WebSocket protocol defines a new feature of a Web application that implements full-duplex communication between the server and the client. Full-duplex communication means that both sides of the communication can send and receive information interactively. It is a new technology that makes Web applications more interactive, such as Java applets, XMLHttpRequest, Adobe Flash, ActiveXOb
