Http://www.cnblogs.com/hanxianlong/archive/2010/04/27/1722018.htmlI have been diving for many years and I suddenly appear today. Haven't written a blog for a long time, not because do not want to write, but because there is no feeling, do not know where to write.The day before yesterday to see a blog "Step by step to create their own Webim", think comet this concept is very interesting, but bloggers use their own set of more complex framework, looks r
Description If you have read one of my previous articlesArticleAsp.net: building scalable comet web applications. You should be able to understand what I will write. I explained the comet technology and explained how to use Asp.net to build scalable applications. However, I think the previous article is a bit like the main line. It demonstrates enough technology, but not enough to include any usefulCode.

When browsing the Web page, suppose there is a new message, how to receive it? The HTTP protocol cannot be actively sent by the server to the client.1, Brush micro Bo, visit the forum bar, want to see the latest information how to do? F5 refresh a bit ok!2, the above one way is passive, assuming the user does not go to refresh the page, will not see the message. How to let the server actively push the message to the client browser, one way is to use setinterval Ajax timed refresh.So. The refresh
Previously, in "reverse Ajax, Part 1: Introduction to Comet" (English version)ArticleI learned the "multipart XMLHttpRequest-based Comet" knowledge, and then implemented it using ASP. NET MVC. For details, see implementing comet Based on multipart XMLHttpRequest using ASP. NET MVC. Today I continue to learn about the comet
My personal understanding is that it looks like a client can subscribe to a server-side event in a Web environment that notifies the client via events. If the server side is implemented with ASP.net, you can take advantage of the. NET event-driven mechanism, which is interesting, as shown in the following sample code. First look at the Web front-end JS code: code is as follows copy code JQuery (function ($) { function long_polling () { nbsp; $.getjson ('/
In B/S model Web applications, the client often needs to maintain continuous updates with the server. Such applications that require high timeliness include stock price queries, real-time commodity prices, automatically updated Twitter timeline, and browser-based chat systems (such as Gtalk. Due to the rise of Ajax technology in recent years, there have also been many implementation methods. This article will describe these methods and demonstrate them with jquery + tornado. It should be noted t
prepare anything special on the server side. It can be processed directly as an HTTP request. The disadvantage is that a large number of requests are wasted. What is comet?The Chinese meaning of comet is probably to indicate that this is a request with a long tail. Like Ajax, comet is a combination of a bunch of Technologies called

Comet Technology PrinciplesFrom Wikipedia: Comet is a web-based technology that enables the server to deliver updated information to clients in real time, without requiring the client to make requests, there are two implementations, long polling and IFRAME streams.In short, a long polling technology based on existing HTTP protocols, all of which are the main reason for this technology is that the HTTP proto
Use Tomcat to implement Comet chat rooms based on iframe streaming First, no picture, no truth, first: This is a chat room Demo Based On Comet. Its function is similar to QQ chat. If there is a new message in the chat process, the server needs to push the message to the browser, So Comet technology can be used here. Comet

" Server Push " technology is "Comet" based on HTTP long connections and no need to install plugins on the browser side . The implementation models for the two Comet applications are described below.AJAX-based long polling (long-polling) modeThe advent of AJAX makes it possible for JavaScript to invoke the XMLHttpRequest object to make an HTTP request, and the JavaScript response handler updates the disp
Comet is a new Web application architecture. In applications developed based on this architecture, the server actively sends messages to the client in asynchronous mode.ProgramPush data without explicitly sending requests from the client. The comet architecture is very suitable for event-driven web applications and applications that require strong interactivity and real-time performance, such as stock excha
based on the HTTP protocol, the HTTP protocol requires the request/Response mode is also immutable, unless the HTTP protocol itself has changed.Comet--- a hack TechnologyThe low latency requirements of data for Web applications represented by instant messaging, the traditional polling-based approach is not enough, and it also brings a bad user experience. So a "server push" technology based on a long HTTP connection is hack out. This technique was named Com
