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

HTML5-WebSocket to achieve chat room example, websocket to achieve chat room The traditional way to implement chat rooms on Web pages is to request the server to obtain related chat information at intervals. However, the websocket function brought about by html5. because websocket allows a connection to the server for

Recently in the websocket of a timely message communication, and then go online to download the example of others. Environment: 1.7jdk+,tomcat7+ The main imported two packages for Tomcat: Catalina.jar, Tomcat-coyote.jar And then put the demo into the project to go, pop-up box is unable to connect, the beginning did not notice, finally thought, is websocket sent the request not to the background. The path

Add the websocket module to skynet and skynetwebsocket Recently, I became fascinated by skynet, with a high code quality and outstanding computing in open-source game server frameworks, whether it's Python firefly, C ++/Python's kbengine, C #'s scut, or nodejs's pomelo, skynet has great advantages in concurrency and commercial applications. Recently, I have been playing h5 games. tornado/django is more than

We have introduced WebRTC and read the example of https://apprtc.appspot.com/on the Internet (which may need to be accessed through a wall). This example is an application deployed on the Google App Engine and relies on the Gae environment, the background language is Python and also relies on the Google App Engine channel API. Therefore, it cannot be run locally or be expanded. After studying the Python sou

We know that the HTTP protocol is a one-way network protocol, after the connection is established, it only allows Browser/ua (useragent) to send webserver request resources, webserver can return the appropriate data. And webserver can not take the initiative to pus

Recent projects in the use of Nginx Push_stream_module push module to implement server-to-client information push, originally only want to achieve this one-way communication needs, but to the client push the message, if you want to let the client give a feedback, There's no way to listen to the feedback event that gets to the client and respond in a timely manner. Later know that Push_stream_module management long connection is based on Pub/sub mode, and as if the module does not give a similar

to use and the Socket is more flexible.5. HTML5 and WebSocketThe WebSocket API is part of the HTML5 standard, but this does not mean that WebSocket must be used in HTML or only in browser-based applications.In fact, many languages, frameworks, and servers provide WebSocket support, such as: C-based libwebsocket.org Socket.io based on node. js

decoupling, in fact, the imitation is still the traditional type of short-link reverse proxy architecture: Nginx/apache +java/php/python/ruby.The client establishes a connection, and the server side needs to use at least two file handles, with one more layer of paths in the middle. Elegant solutions that can be viewed from the Socket.io. A set of server-side programs, while providing several protocols for terminal selection. In fact, an MQTT broker m

IP protocol to address the hosts in the network. We know that the IP protocol used by the network layer can help us to locate the target host based on the IP address, but there may be multiple applications running on one host, and how to communicate with the specified application is specified by the TCP or UPD address, or the port number. This makes it possible for a Socket instance to uniquely represent a communication link for an application on a host.
