AMIGOS, ESTOU TENDO ALGUNS PROBLEMAS COM MEU SERVIDOR SQUID,
PRECISEI FAZER UM BLOQUEI DE PAGINAS NO MEU SQUID, SO QUE AGORA PRECISO LIBERAR ALGUNS USUARIO PARA TER ACESSO TOTAL, SO QUE JA TENTEI DE VARIAS FORMAS, MAS NAO CONSIGO, POR ISSO PESSO AJUDA DE VCS.
ESTOU POSTANDO ABAIXO MINHAS REGRAS.
OBRIGADO PELO ATENÇÃO
ACHO QUE MEU PROBLEMA E NA ORDEM DAS REGRAS.
