It should be possible to set the cookie domain to '.xxxxxx.net' - all servers below that domain will be sent that cookie then.

$c = new CGI::Cookie(-name    =>  'foo',
                     -value   =>  'bar',
                     -expires =>  '+3M',
                     -domain  =>  '.xxxxxx.net',
                     -path    =>  '/cgi/foo/bar'
                     -secure  =>  1
                     );
