I get along just fine without CGIS. Its up to the app to put the session id into any html if that's desired to work around cookieless browsers.

package Camp;
use strict;
use warnings;
use base qw/CGI::Application/;
use CGI::Session;
use DBI;

sub setup {
  my $self = shift;
  my $q = $self->query;

  my $dbh = DBI->connect($self->param('DBH_DSN'),
                         $self->param('DBH_USER'),
                         $self->param('DBH_PASS'),
                         $self->param('DBH_OPT'));
  $self->param( dbh => $dbh );

  my $session = CGI::Session->new
    ( "driver:PostgreSQL",
      $q,
      { Handle => $dbh } );
  my $session_id = $session->id;

  $self->param( session => $session );
  $self->param( session_id => $session_id );

  return;
}

sub cgiapp_prerun {
  my $self = shift;

  my $session = $self->param('session');
  my $session_id = $session->id;

  # Save the session cookie
  $self->header_props
    ( -cookie => CGI::Cookie->new( -name => 'CGISESSID',
                                   -value => $session_id ) );


  return;
}

sub teardown {
  my $self = shift;

  $self->param('session')->flush;
  $self->param('dbh')->disconnect;

  return;
}
