克服 PHP/MySQL 的方法 + Ajax/彗星/长轮询？
我现有的网站采用 PHP/MySQL 框架。他们非常忙碌，聊天、事件、vs（间隔）ajax 实现也增加了服务器负载。现在网站变得越来越大，所以我需要更改为长轮询/comet，但 apache 不太擅长这些，而且大多数 comet 服务器都是用 Java 完成的。比如 cometd、www.stream-hub.com、activemq。
是否有任何服务器实现可以使用，而无需在 java 中重新编码 ajax 页面或最少在 Java/Python 中编码。
I have existing websites with PHP/MySQL framework. They are very busy and chat, events, vs (interval) ajax implementations added to server load as well. Now websites are going bigger so I need to change to long polling/comet but apache is not very well with these and most of the comet servers are done in Java. Like cometd, www.stream-hub.com, activemq.
Are there any server implementations that I can use without re-coding the ajax pages in java or least coding in Java/Python.

您可能想看看 Ajax Push Engine，它是一个与 apache 配合良好的推送引擎。服务器部分是用 C 编写的，因此您无需担心运行 java 或 python 服务器。
此外，您可能还想研究新的 HTML 5 Web 套接字规范。 Web Sockets 将允许在 JavaScript 中直接进行套接字编程，这通常消除了长轮询/comet 的需要。请记住，HTML 5 尚未被所有浏览器完全接受。
You may want to take a lookg at Ajax Push Engine its a push engine that works well alongside apache. The server portio is written in C so you dont need to worry about running a java or python server.
Also you may want to investigate the new HTML 5 web socket specification. Web Sockets will allow for direct socket programing in javascript, which often removes the need for long polling/comet. Keep in mind that HTML 5 hasn't been fully embraced yet by all browsers tho.
您可以尝试 SaaS comet 解决方案，例如 WebSync On-Demand。无需重新编码太多，您只需在页面中订阅，然后从服务器发布到该订阅者即可。由于它是一个 SaaS 解决方案，因此它与 PHP 配合得很好 - 甚至还有一个预构建的 PHP 库，完全可以满足您想要做的事情。
You could try a SaaS comet solution, such as WebSync On-Demand. There's no need to recode much, you can just subscribe in your page, and publish from your server to that subscriber. Since it's a SaaS solution, it works great with PHP - there's even a pre-built PHP library for exactly what you're trying to do.
