First, WebSocket Introduction:When it comes to web real-time push, you have to say websocket. Before the advent of WebSocket, a number of sites were typically used to implement real-time push technology.is polling (Polling) and comet technology, comet can be subdivided into two implementations, one is the long polling mechanism, which is called the flow technolog

WebSocket initiates a single request, the server does not need to wait for the customer service side, the client at any time can also send messages to the server, reducing the delay in polling time. The difference between polling and WebSocket. Once the resume is connected, the server can send the client multiple times.HTTP-based real-time messages are quite complex, and the state of maintaining a reply in

Recently, a web game was created as needed. In a certain period of time, the page needs to be refreshed in real time. Currently, the general idea of website creation is to use js polling. Because it is an innovative small project, friends in the same group proposed the WebSocket mentioned in html5. they first conducted technical research. Currently, java does not support many websockets. Few websocket imple

What is WebSocket? WebSocket is a persistent protocol, which is relative to HTTP non-persistence. to give a simple example, The life cycle of http1.0 is defined by the request, that is, a request, a response, for HTTP, this time the client and server session to this end, and in http1.1, slightly improved, that is, the addition of keep-alive, that is, in a Multiple request requests and multiple response acce

Before the company's real-time chat with the regular round, has always felt very unscientific, the recent backstage said configuration good socket server, I am happy to prepare with asyncsocket, but told me to use WebSocket, based on HTML5, A new bidirectional communication protocol (--websocket) is proposed in HTML5, this paper attempts to use this technology to realize the above real-time chat function.Af

The case is developed and run in the apache-tomcat-8.0.15 and jdk1.8.0_25 environments. However, the title is Java7, it does not affect, the code does not involve any jdk1.8.x-related code. In addition, the reason to clear the software version, one is to ensure that the case can have a clear implementation of the background, the second is websocket to achieve tomcat7.x and tomcat8.x there is a great difference.The Java API for

I. WebSocket Brief INTRODUCTION WebSocket protocol is HTML5 a new protocol. It implements the browser and server Full-duplex communication (Full-duplex). A handshake at the beginning requires an HTTP request to complete the handshake. With the development of Internet, the traditional HTTP protocol has been difficult to meet the increasingly complex requirements of web applications. In recent years, with t

WebSocket WebSocket is just a network communication protocol. Like HTTP, FTP and so on are network communication protocols; Don't think much of it; WebSocket is a protocol for persistent network communication, as opposed to HTTP, a non-persistent protocol; The relationship between WebSocket and HTTP There are in

The distribution of Message Centers is achieved through establishing a persistent connection between websocket and the backend server. The advantage of this method is to save network bandwidth, second, users can receive messages sent from the backend in real time. netty is used in the backend implementation. After stress testing, each server can withstand 0.5 million persistent connections, that is, 0.5 million users at the same time (only one persist

WebSocket is a simple demo program based on javaweb + tomcat, and websocketjavaweb As required by the project, after the frontend initiates a request to the background, the background must be divided into multiple steps for relevant operations, and the time required for completing each step cannot be determined. If ajax is used to repeatedly access the background to obtain real-time data, it is obviously not suitable, whether it is a waste of resource

WebSocket initiates a single request, the server does not need to wait for the customer service side, the client at any time can also send messages to the service side, reduce the polling time delay. After a connection has been made, it can be sent multiple times to the client. Is the difference between polling and WebSocket.HTTP-based real-time messages are quite complex, maintaining a state of call in a stateless request adds complexity, and cross-d
