On top of the other responses, I'd add:
Your application must keep track of a 'session'. The main ways to do
that are:

o Add a hidden field to each CGI form, in which you send out to the
client the id of their session, so that when the use submits the form
you get back their id. This is my preferred alternative

o Add the session id to a cookie sent from your code, which you get back
later from the client. This is a commonly-used method

o Add the session id to the URL. This method has the most problems, and
is not recommended.

The session id is generated by CGI::Session.
