HTTP 长连接的“服务器推”技术》，里面已经说得非常详细了，我就不再复述了。<img src ="http://blog.csdn.net/tongdoudpj/aggbug/4174272.aspx" width = "1" height = "1" /><img

年的夏天，偶然在网上闲逛的时候发现了 Comet 技术，人云亦云间，姑且认为它是由 Dojo 的 Alex Russell 在 2006 年提出。在阅读了大量的资料后，萌发出写篇 blog 来说明什么是 Comet 的想法。哪知道这个想法到了半年后的今天才提笔，除了繁忙的工作拖延外，还有 Comet 本身带来的困惑。 <img src

Comet － 使用 HTTP 长连接、无须浏览器安装插件的两种“服务器推”方案：基于 AJAX 的长轮询方式；基于 iframe 及 htmlfile 的流方式。最后分析了开发 Comet 应用需要注意的一些问题，以及如何借助开源的 Comet 框架－pushlet 构建自己的“服务器推”应用。 <img src
