Tell me some Http-streaming tutorial or example

Could you tell me some http-streaming tutorial or example ( used also by Gmail ) ?

I want to create a simple chat 开发者_StackOverflowfor college project.

Attention: I am talking about Http-streaming and NOT long-polling.

Thanks ;)

Check here. Some cool intro about Comet. There is also a mention for Jetty and its free chat client but they are in Java not PHP. Will keep looking and post if I find something useful with PHP. Just FYI, jquery has a plugin for comet but I haven't tried it yet.

"Comet" is just an umbrella term that includes HTTP streaming.

For some good examples, you can check out our WebSync demos.

For some tutorials on using it, you can check out the tutorials.
