  1. Ola Senhores(as).

    Existe alguma regra específica para que possa ser feito o cache do youtube, seja via mod-rewrite no squid ou no mikrotik (que acho difícil, mas não impossivel).

    Obrigado galera.

  2. 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.
