[This article is original, if reproduced, please indicate the source http://blog.csdn.net/yl02520/article/] WebSocket is based on TCP like the HTTP protocol, so they are all reliable protocols, and the WebSocket send function that Web developers invoke is eventually transmitted through TCP's system interface in browser implementations. WebSocket and HTTP protoco

of data to pay a huge price, it is very uneconomical, occupy a lot of broadband.Disadvantage: can cause excessive unnecessary requests, waste traffic and server resources, every request, reply, wasted a certain amount of traffic on the same header informationHowever, the appearance of websocket can compensate for this shortcoming. In WebSocket, only the server and browser are required to perform a handshak

[This article is original, if reproduced, please indicate the source http://blog.csdn.net/yl02520/article/] Browser has supported the HTTP protocol, so why develop a new websocket protocol? 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

HTML5 Study Notes (5)-WebSocket and message push, html5websocket In B/S-structured software projects, sometimes the client needs to obtain server messages in real time, but the default HTTP protocol only supports the request response mode. This can simplify the Web server and reduce the burden on the server, the response speed is accelerated because the server does not need to establish a communication link with the client for a long time, but it is n

know the bytes representing the length of the data at the end of the number, such as we take example 60, this value is between 0~125, so the second byte itself represents the length of the original data (60 bytes), so we can grab 4 bytes from the third byte, This string of bytes is called "Masks" (mask?), the data after the mask, is the actual ... 's brother. Said to be a brother, because this data is actually based on the mask to do a bitwise operation, the method of obtaining the original dat

Introduction and principle of websocket WebSocket protocol is a new protocol for HTML5. It implements browser-to-server full-duplex communication (Full-duplex). The first handshake needs to be done with an HTTP request. --Baidu Encyclopedia Purpose: Instant messaging instead of pollingThe Instant Messenger on the website is very common, such as the QQ of the webpage, chat system and so on.

), the next eight bytes represent the Data Length. With this judgment, we can know the number of bytes that indicate the length of the data to end at. For example, 60 is used, and the value is between 0 and ~ Between 125 bytes, so the second byte itself represents the length of the original data (60 bytes), so from the third byte, we can capture 4 bytes, this string of bytes is called "masks" (mask ?), The data after the mask is the actual data... Brother. This is because the actual data is obta
