Ruby on rails chat application over port 80, which hosts the agnostic site (without flash and websockets)

It is required to create a chat application (i.e. a bi-directional message sent to several connected clients). I looked at the Faye gem, but it opens a new port except port 80.

The big problem is that if the client is behind a firewall, all access to ports other than 80 is limited, and not all hosting sites provide support.

There is no client registration mechanism in the ActionController :: Live component so that a message cannot be sent to registered clients when a certain event occurs.

You are looking for a solution in which live clients are stored in a collection (an array or something like that), and when any of the living clients sends a message, the collection can be repeated and messages can be written on it. All this should happen only through port 80.
