http的反向推送通常使用"长轮询"或"长连接"的方式。 所谓"长轮询"是指客户端发送请求给服务器，服务器发现没有数据需要发送给客户端于是hold住不及时返回，等有数据需要发送给客户端时，进行回复，然后关闭连接，客户端收到回复后再发送新的http请求，以便服务器能有对应的请求用于消息的反向推送。 而"长连接"是在长轮询的基础上增加"keep-alive"属性，服务器收到请求后不直接回复，等有数据需要发送给客户端时再进行response，但是并不关闭连接，这样客户端收到服务器的response后在同一连接上再次发送http请求。 在ejabberd的实现中，采用了bosh技术来完成对应的工作，具体定义可参考： 英文: http://xmpp.org/extensions/xep-0124.html 中文: http://wiki.jabbercn.org/XEP-0124 大概实现原理：ejabberd收到一个客户端http请求后会为该客户端最终创建三个进程：ejabberd_http, ejabberd_http_bind, ejabberd_c2s。 ejabberd_http进程不断的从对应的socket上收客户端的请求，并转发交给对应的ejabberd_http_bind进程进行处理，然后同步等待处理结果，并将结果返回给客户端。 init() -> ... receive

I'm developing a real time chat app. After searching around for a while, I found Ejabberd and Erlang is a good option. The question is the Ejabberd is not providing all the functions I need. I need some custom features such as location based matching and anonymous login. So how to development custom functions on top of Ejabberd? write modules for it? or develop another standalone server app (web or other kind of server app) to interact with it? update: another concern is the way we add custom functions/features should be scalable. You can write your custom modules which hook up to events in
