  1. Bom dia Amigos !

    Tenho um squid rodando em um webserver, funcionando como proxy transparente e barrando alguns sites por palavras chaves. Ate aki tudo blz, os sites que contem determinada palavra estao sendo barrados perfeitamente, mas de uns tempos para ca descobrimos uma falha, se seu digitar o parametro ?=meudominio o site passa a ser acessado, sem figuras mas os links todos estao la. Por exemplo : se eu digitar www.orkut.com ele barra e se eu digitar www.orkut.com/?=meudominio ele passa pelo block

    Será que eu tenho de setar alguma confi no squid.conf ? Por favor nao sei mais o implementar para sanar essa falha


    Desde ja agradeco a atenção !! e que a força esteja com vcs
