A widely-used approach is to give the user a 'session-id' and
store all the data you want to associate with that 'session'
someplace on the server.
The two issues are then:
1) HTTP is stateless, so how do you identify the 'session-id'
for each request?
2) CGI starts up a new *process* for each request, so how do
you share the associated data?
