to request a protocol upgrade (or in this case a protocol switch) to which the server can respond WI Th HTTP status (switching protocols) if it agrees. Assuming the handshake succeeds the TCP socket underlying the HTTP upgrade request remains open and both client and server can use it to send messages to each other. The Spring Framework 4 includes a new Spring-websocket module with comprehensive websocket

.@OnError The method is invoked when an exception is found on the server, such as a protocol error.

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

In HTML5 specifications, my favorite Web technology is the rapidly becoming popular WebSocket API. WebSocket provides a popular technology to replace the Ajax technology we have been using over the past few years. This new API provides a method to effectively push messages from the client to the server using simple syntax. Let's take a look at HTML5 WebSocket API

tamper with encrypted connections, and the data you send is encrypted and not easily stolen by others. Use a TCP load balancer in front of the WebSocket server instead of using an HTTP load balancer, unless an HTTP load balancer preaches itself to support WebSocket. Do not assume that browsers support WebSocket, although browser support

framework of python (tornado provides the tornado. websocket module ). Of course, you can also use socket. io is a js language server designed for webSocket. it is very easy to use and is compatible with browsers that do not support webSocket (implemented in flash or comet ). I personally prefer tornado, which has been used for background development for several

TCP/IP, WebSocket and MQTT According to the OSI network layering model, IP is the Network layer protocol, TCP is the Transport Layer protocol, and HTTP and Mqtt are the application layer protocols. Between the three, TCP is the protocol for HTTP and Mqtt at the bottom. Everyone is familiar with HTTP, here is a brief introduction to MQTT. The MQTT (message Queuing Telemetry Transport, Messaging queue telemetry transmission) is an Instant Messaging pro
