Re: push data from server to client web browser

["Raul A. Jager W." <raul@xxxxxxxxxx>]

In order to push, the browser will need to be open, and probably
pointing at the server.  Refresh or Ajax will do a good job of pulling
evry x secconds.

If you realy need the user to receive the message, you will need to run
a remote command (also chain him to his desk) or use a message system.

It will be very nice to port "Jabber" or something similar to the i.
