This article series shows how to use reverse Ajax (Reverse Ajax) technology to develop event-driven Web applications. The 1th part of the series describes reverse Ajax, polling (polling), streaming (streaming), comet, and long polling (long polling). You've learned how Comet uses HTTP long polling, which is the best way to reliably reverse Aja

This is a creation in Article, where the information may have evolved or changed.

In addition, there is the WSS protocol, which represents the encrypted WebSocket protocol, which cor

Spring WebSocket Detailed The spring framework supports WebSocket starting with version 4.0, and I'll detail the Spring WebSocket library. The content includes how the spring framework supports WebSocket messaging in Web applications, and how to leverage the STOMP protocol as a sub-protocol to the application layer's p

Overview HTTP protocol is a stateless protocol, the server side itself does not have the ability to identify clients, must use external mechanisms, such as session and cookies, to maintain a dialogue with a specific client. This is more or less inconvenient, especially in the context of server-side and client needs to continuously exchange data (such as network chat). To solve this problem, HTML5 proposed the browser's WebSocket API. The primary rol

Old boy It education Alex Python teaching director teaches you to know WebSocketThe WebSocket protocol is a new protocol based on TCP. WebSocket was originally referred to as a TCP connection in the HTML5 specification as a placeholder for the TCP-based socket API. It implements browser-to-server full-duplex (Full-duplex) communication. The essence is to keep the

1. What is WebSocket? WebSocket is a protocol specification proposed by HTML5, referring to rfc6455. WebSocket the specification of a communication, through a handshake mechanism, between the client (browser) and the server (webserver) can establish a TCP-like connection, so as to facilitate communication between the c-s. Before the advent of

WebSocket is a network technology that HTML5 started to provide full duplex communication between the browser and the server. In the WebSocket API, the browser and server only need to do a handshake, and then a fast channel is formed between the browser and the server. The data can be transmitted to each other directly between the two.The Cocos2d-x engine integrates libwebsockets, and encapsulates an easy-t

How to fully control sessions? Check WebSocket cross-site hijacking (1) WebSockets is an HTML5 feature that provides full-duplex channels for a single TCP connection. Its persistent connection function makes it possible to build real-time applications in B/S mode. Websockets is often used in WEB applications with chat functions. The following figure illustrates the websockets used by an APT attack: Popular Science: Same origin policy: the Same origi
