which is the proper way to push notifications to another webserver

Question

We have an API built on Rails, and processing some stuff with resque. After the process now, I need to send a notification to the client (which is an app built with Play Framework, that sends a json file to the API with the data to be processed with resque).
I found Faye, Private Pub and a lot of others but they only have examples to notify a page (like a chat window and so), and not a webserver.
any ideas? thanks a lot

Answer 1

We've done it with faye. Works pretty well
