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 side of the Duplex Communication protocol

Today, many Web sites are polled for the technology they use to implement push technology. Polling is at a specific time interval (such as every 1 seconds), the browser sends an HTTP request to the server, and then the server returns the latest data to the client's browser. This traditional pattern brings with it the obvious drawback that the browser needs to constantly make requests to the server, but the header of the HTTP request is very long, and the data contained in it may be a small value

ObjectiveRecently in a project, need to use to WebSocket, before to WebSocket not very understanding, so took a little time to familiarize with WebSocket.Between browser and server communication, traditional HTTP requests are not ideal in some scenarios, such as live chat, real-time games, etc.It faces two main drawbacks:
The "Real time" of the message cannot be achieved;
Server can not activel
Two URL schemes of WebSocket protocolNon-encrypted traffic between WS client and serverEncrypted traffic between the WSS client and serverWebSocket secure means that WebSocket connections using Transport Layer Security (SSL) use HTTPS security to secure HTTP connectionsConstructors for 1.WebSocketvar ws = new WebSocket ("ws://www.websocket.org"); 2.
Use html5 websocket to implement a chat room.
What is websocket?
The WebSocket protocol is a new protocol introduced by html5. it aims to implement full duplex communication between browsers and servers. Those who read the link above will surely have some knowledge about how low efficiency and high consumption (polling or comet) have been done in the past. In th
First knowledge of WebSocket protocol, first knowledge of websocket1. What is the WebSocket protocol?
RFC6455 is described as follows:
The WebSocket Protocol enables two-way communication between a client running untrusted code in a controlled environment to a remote host that has opted-in to communications from that code. The security model used for this is the

Function: Use websocket technology to display the log information on remote server in real time on the browser of operation and Maintenance toolIn general, we need to present the information in the deployment process in real time when the OPS tool is deployed, or show the program log to the developer in real time in the browser. Are you still using AJAX to get the server log every once in a while? Out, try
time_ Wait state of the connection, however, if set keep-alive timeout time, such as Nginx is keepalive_timeout, a period of time without communication time-out after the server actively shut down the connection may also cause the server to appear time_wait state, It is also important to set this time-out if you do not set a time-out period that also causes a certain amount of wasted resources, which are used to connect without sending data.In essence, although the HTTP1.1 can maintain a persis
addition, the header information exchanged between the server and the client is small.
WebSocket is not limited to Ajax (or XHR) communication because Ajax technology requires a client to initiate a request, and WebSocket servers and clients can push information to each other;
