Actually, all those parameters are still being passed along, you are just not attaching them to the uri. Passing parameters to $req->content() is adding the parameters to the content portion of the HTTP packet... The port number makes no difference. Hmmm...

This is how I would do it (in case anybody was wondering):

use strict;
use LWP::UserAgent;
use LWP::Debug qw(+);
use HTTP::Request;

my $ua = LWP::UserAgent->new;
$ua->agent("Wobbygong Shark/ 0.1");

# Create a request
my $req_method = 'GET';
my $url = "http://thebigwobbygongsharkonheat.aquaworld.tv:8081/";
my $res;
my $content_params = 'oneandthesame=;';

my $req = HTTP::Request->new(
                  $req_method=>$url,
                  HTTP::Headers->new(
                  'Content-Type'=>'application/x-www-form-urlencoded')
);
$req->content($content_params);
$ua->request($req);
