Hi Jaldhar

Very nice indeed.

I suggest including a discussion of maintaining state, in this sense:

o While the CGI script is running, it has local memory, accessed via $self ->
param(x => $y). When the script exits, this memory is lost forever.

o The CGI script can save state in visible and hidden CGI form variables, which
live on by going out to the web client and back, and hence survive until the
next invocation of the script, but not beyond that, unless this process is
repeated.

o The CGI script can save state in session data in a database, via a superb
plug-architecture, and this data lives on independently of the CGI script
itself, and of the CGI form. Such data is normally recalled by the next
invocation of the CGI script, and is often purged via an off-line process.

Explaining the purpose and uses of these 3 types of memory are left as
homework...
