I am humbly aspiring to learn mod_perl by converting an existing, fairly complex, cgi application. Though I have been pretty successful getting most scripts to run under ModPerl::Registry, I'm getting remembered cgi.pm params. Which leads me to believe I have no clue on what gets shared. I have one module called Security.pm with no global vars. I call a function which creates $q=CGI->new;, checks authorization and displays a login page with a param('login_name') if they are not logged in yet. I have many different scripts with the following basic format: 
sub main {
   my $q = CGI->new;
   my $func = $q->param('func');
   if ($func eq 'somefunc') { &somefunc }
}

sub somefunc {
    my $q = CGI->new;
}

My problem is that if I use param('login_name') in &somefunc it has a retained value from elsewhere, like the one entered in during login from the Security module. I tried '-override=>1' on that param and received an error that indicated I could not change the value of that param.

So are $q vars being somehow loaded up once in mod_perl and never cleared with each CGI->new?

I could certainly use some tips on understanding variable usage and sharing/not sharing under mod_perl. I am searching through 'practical mod_perl' as well.

I'd appreciate any pointers or direction on how to properly use modules like CGI.pm or how modules behave after they are loaded and compiled in mod_perl.
