When you create your HTTP::Request object, instead of:
$req = new HTTP::Request 'POST','http://www.eliteweaver.co.uk/testing/ipntest.php';

Put your parameter hash in as the third argument (after you've added your new param):
$req = new HTTP::Request 'POST','http://www.eliteweaver.co.uk/testing/ipntest.php',$q->Vars;

You can then delete the next two lines,

$req->content_type('application/x-www-form-urlencoded');
$req->content($q);

That doesn't seem to work either, I think it is looking for the string as it is received by my program with the addition of the cmd variable. I will just create the CGI object later on when I process the variables.

use strict;
use CGI;
