simple solution would be to add a timeflag in the perl script and check against it.
don't know whether you can achieve this via squid...
in this case 2 hours (7200):
if (!defined($logged_in{$_})) {
$logged_in{$_} = time();
print "ERR\n";
} elsif ($logged_in{$_} < time() - 7200) {
print "ERR\n";
} else {
print "OK\n";
}
