Thanks for above, JavaFan!

I'm trying to grasp the concept before I use mod_perl, so please bear with me if my questions sounded silly.

I'm trying to make sense of 'The issue with mod_perl is that modules get only compiled "once"'. Let's say I've a variable (my $score) in a module that stores the score of a user, say, playing a game. When another user comes online, or for that matter, when several users appear, will the variable correctly store the value for each of the user when the script (that calls the said module) is run?
