ajax websocket

Preface Today, users expect fast and dynamic applications that can be accessed through the web. This article series shows how to use reverse Ajax (reverse Ajax) technology to develop event-driven Web applications. Part 1 of the series describes reverse Ajax, polling, streaming, Comet, and long polling ). You have learned how comet uses HTTP long polling. This is

Here I draw a diagram showing the handshake part of the WebSocket connection between the client and the server, which can be done very easily in node, because the net module provided by node has already encapsulated the socket socket, and developers only need to use Consider the interaction of the data without having to deal with the establishment of the connection. and PHP does not, from the socket connection, establishment, binding, monitoring, and

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

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
