Youtube, afinal caheia ou não ???

Apesar de tentar que alguem me desse uma luz, me surpreendi!(ambuguidade).

Achei um script que esta rodando em meu server e fez o cache do youtube senhores.

Pena que ele usa o squid fora do MK e deve ser a versão 2.6 ou acima e ter o perl para rodar o script de redirecionamento vi HIT, seque o script.
