Nginx HTTP Push Module v0.69

This module turns Nginx into an adept HTTP Push and Comet server. It
takes care of all the connection juggling, and exposes a simple
interface to broadcast messages to clients via plain old HTTP requests.
This lets one write live-updating asynchronous web applications as
easily as their oldschool classic counterparts, since the code does not
need to manage requests with delayed responses. The module implements a
no-frills publisher/subscriber protocol centered on uniquely
identifiable channels. It is an order of magnitude simpler and more
basic than similar protocols (such as Bayeux).

Looks very interesting!

Is there an extension point whereby I can program a Java application,
example, to participate a channel? Furthermore what if I want to create
modulator’s console to modulate a chatting room, preferably in a
language of
my choice?

Take a look at . You would have Java send
HTTP requests to urls of your choosing to interact with the server –
both to publish messages and subscribe to communication channels. If you
want any sort of moderation functionality, you will want to keep the
publisher locations visible only to your application and have clients
send messages through your application (which will implement your
desired moderation logic)

Or the module could send messages via a sub-request to an URL that is
associated with my monitoring application and dispatch the message
to the result of the sub-request. It would make a good mechanism to hook
an interceptor it seems.

Hey Leo,
nice work - looks awesome. I’ve been playing around with the server and
wondering if it’s possible to be member of multiple channels with one
connection. Like being in a chat with 3 people. I could open 3 long
requests but would have to trick around with domain names due to the
2-connection limit then.


Err…maybe something like


Channel multiplexing will be available soon, maybe in the next release.

Definitely looking forward to it!
