Can anybody offer guidance so i can understand something about mod_perl? I put this example together in hopes that it would illustrate where i'm fuzzy about mod_perl, modules and consistent memory. Here's some background. Modules are brand new to me, i have only written a few in local testing. Mod_perl has been on my server for roughly 12 hours. It has been successfully tested. $ENV{'MOD_PERL'} returns (mod_perl/1.23). And a few benchmarks have made me smile.

I want to explore the abilities of mod_perl and sharing. Under mod_perl, i wanted to call ModCounter::TotalRun and return a incremental number which would represent the number of times that call was made. Without mod_perl, my ModCounter::TotalRun always returns 1. I expected that.
With mod_perl, i get a one digit number that changes randomly (random = "jameshasnoclue"). I read about this in the mod_perl documentation. And it explained how to stop the randomness from occuring and bring the result back to a consistent 1.

But i want the opposite. I want the counter to grow every time ModCounter::TotalRun is called. I was hoping that i could then connect several perl scripts on my server to ModCounter.pm. Each script could call the module ModCounter::TotalRun numerous times and increment the counter.

Here's the attempted module: ModCounter.pm 
package ModCounter;
use Exporter;
@ISA = qw(Exporter);
use vars qw($cnt);
@EXPORT_OK = qw(TotalRun);
sub TotalRun{
$cnt++;
return $cnt;
}

1;

And here's the script which calls ModCounter.pm. 
#!/usr/bin/perl -w
use strict;
print "Content-type:text/html\n\n";
use ModCounter;
print "cnt=".ModCounter::TotalRun;
exit;

I was hoping to get an incremental count when it runs in mod_perl. Thanks for monkin.
