If $my_object does not need to be different for different child httpds,
then simply put it in the parent httpd. Or better still use
Apache::Session (since you already have a neat DBI-accessible database
setup). From the perldoc of Apache::Session :
use strict;
my %global_data;
eval {
tie %global_data, 'Apache::Session::File', 1,
{Directory => '/tmp/sessiondata'};
};
if ($@) {
die "Global data is not accessible: $@";
}
my $dbh = DBI->connect($global_data{datasource},
$global_data{username}, $global_data{password}) || die $DBI::errstr;
undef %global_data;
Of course, you can use Apache::Session::[MySQL|Oracle||DBI-d/b] instead
of Apache::Session::File.
