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... -- Cheers Ron Savage, [EMAIL PROTECTED] on 5/09/2005 http://savage.net.au/index.html Let the record show: Microsoft is not an Australian company --------------------------------------------------------------------- Web Archive: http://www.mail-archive.com/[email protected]/ http://marc.theaimsgroup.com/?l=cgiapp&r=1&w=2 To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
