有没有人想过为什么 Facebook 聊天这么快?即使在没有 WebSocket 的 IE 中.
Has anybody ever wonder why Facebook chat is just so really really fast? even in IE without WebSocket.
不是唯一的方法是在JS中设置间隔来检查新消息吗?但我觉得(Facebook 聊天框)就像是即时反应.
Isn't the only way is to setInterval in JS to check for new messages? But I feel it (Facebook chat box) like having instant reaction.

推荐答案
您所描述的即时聊天通常是通过一种称为长轮询"的东西来实现的，或者，如果我们谈论的是 AJAX，则是彗星"(维基百科 谈论).轮询往往会给 Apache 服务器带来压力，但有一些专门的服务器可以处理它，例如 APE.我不确定，但我认为你可以用 NodeJS 和 NGINX 很好地处理了压力.
The instantaneous chat you're describing is generally acheived by a something called "Long Polling" or, if we're talking about AJAX, "Comet" (Wikipedia talks about it). Polling tends to strain Apache servers, but there are some specialized servers to deal with it like APE. I'm not sure but I think you can do the same with NodeJS and NGINX handles the stress pretty well.
