Not that I know of, no. Because as the first poster wrote,
HTTP is stateless, meaning that your server program has
no way of knowing what's going on with the client (the
browser).
The only way around this is to implement your chat program
in Java--the java client can keep an open socket to the
server, so when the socket closes, the server knows that
the client has "logged off."
Of course, this probably also wouldn't work w/ your text-only
browsers. :) | [reply] |
Actually you might be able to get away with only a 1 pixel sized java applet that could maintain a connection to the serverl. (The only purpose it would serve would eb as a presence detector.)
