my $sock = new IO::Socket::INET (
                                 PeerAddr => 'www.example.org',
                                 PeerPort => '80',
                                 Proto => 'tcp',
                                );
die "Could not create socket: $!\n" unless $sock;
print $sock "GET /index.html HTTP/1.0\r\n";
print $sock "Host: www.example.org\r\n";
print $sock "Cookie: test=quest\r\n\r\n";
print while <$sock>;
close($sock);
