对于所有的东西的重要来源彗星是彗星每日。不幸的是，不是所有的更新，往往更多，但也有一些奇妙的老文章在那里。它是由家伙一直在开发彗星解决方案超过10年了贡献。
A great source for all things Comet is Comet Daily. Unfortunately it's not updated all that often any more but there are some fantastic old articles in there. It's contributed to by guys that have been developing Comet solutions for over 10 years.
彗星似乎得到不正确的捆绑意义只是一个特定的连接机制被使用，但它实际上是一个范例，实时推送，从服务器到客户端。彗星服务器可以使用HTTP流，HTTP长轮询，经典轮询和WebSockets的。
Comet seems to get incorrectly bundled as meaning just one particular connection mechanism is used, but it's actually a paradigm for realtime push from server to client. Comet servers can use HTTP Streaming, HTTP Long-Polling, classic polling and WebSockets.
如果您有兴趣在最新的Push技术，那么你应该看看的WebSockets 这是一种标准化的方法不仅服务器到客户端推送，而且服务器和客户端（Web浏览器和其他客户端）之间的双向实时通信的
If you are interested in the latest Push Technology then you should take a look at WebSockets which is a standardised approach to not only server to client push, but also bi-directional realtime communication between servers and clients (web browsers and other clients).
目前的一些趋势推技术有：
Some current trending push technologies are:
- socket.io
- Hosted WebSockets services such as Pusher - who I work for
- Faye for self hosted Ruby or Node dev
- SignalR for IIS and .NET
- There are many more and more information on realtime web technologies can be found on this guide.
