Subject: Re: Sessions or cookies
Hello,
In my own opinion, session score a bit over cookie, but only a
little bit. Some servlet engine implement session using cookie. It sends a
cookie holding "session no." to the client. When client call back to server,
it retrieves this cookie and see if there is a session with this session
no.
You can also implement such a thing like this using cookie,
say "your own session table". HttpSession provide everything you may want for
general session but if you want something advance or specific, try implement
your own.

Siros
