Res: [CentOS-pt-br] Site não abre quando o squid esta habilitado
by Daniel Bessas 23 Sep '08

Ricardo, boa noite. Pelo que vi no seu squid.conf, você tem um txt de site proibidos....aqui na empresa tambem é configurado desta forma, mas coloquei um txt de sites aceitos....coloque as seguintes linhas no seu squid.conf e faça um teste: obs.: no arquivo aceitos.txt, você coloca todos os sites que por algum motivo o squid barrou.... não sou expert, mas espero ter ajudado....qualquer dúvida, favor entrar em contato.

Ola Pessoal Estou com o seguinte problema quando habilito o squid o site http://www.metlife.com.br/ não abre mas quando desabilito o squid o mesmo passa a funcionar. Os demais fuincionam normalmente, somente este site fica ser carregar e da a mensagem de timeout no navegador. Segue abaixo a configuração do squid. Desde ja agradeço.
