Broc--
Thanks for the useful code. But I thought since it was placed in the
Session_OnStart sub, that it would create an empty array reference for each
new session, not script. Is this not the case? Now Script_OnStart I
understand happens each time a script runs, but I thought the former sub was
independent of how many scripts run in a given session. Even though I am
inquisitive to the answer of this question, the code you supplied may very
well be part of the answer I implement.
Robert--
Thanks so much for clearing that up for me. I had no idea how Session
handled stuff internally, so it was easy for me to fall into that trap.
Your example helped me tremendously.
Regards,
Thom

This code will assign an empty, anonymous array to $Session->{'history'}
each time your page loads, thus clearing it out.
You might create subs that check for it to be undef at either "get" or
"put" times....
sub get_history {
my $list_ref = $Session->{'history'};
$list_ref = [] unless $list_ref;
return $list_ref;
}
sub put_history {
my $list_ref = shift;
$list_ref = [] unless $list_ref;
$Session->{'history'} = $list_ref;
}
