I would suggest that your problem is using Matt Wright's cookie library. Try CGI.pm and you'll find that it is all integrated for you. From the CGI documentation:

$cookie = $query->cookie(-name=>'sessionID',
                         -value=>'xyzzy',
                         -expires=>'+1h',
                         -path=>'/cgi-bin/database',
                         -domain=>'.capricorn.org',
                         -secure=>1);
print $query->header(-cookie=>$cookie);
