[FUG-BR] OT: lusca só da TCP_MISS, nenhum HIT

[Enio Marconcini # www.Enio.Pro.Br]

pessoal, estive analisando o access.log de 2 servidores com lusca, e percebi
que só tenho TCP_MISS, nenhum hit, muito estranho, a maioria dos sites
acessados possuem conteúdo que seriam cacheados......

o squid.conf é bem simples, só bloqueio algumas extensões, de resto, é tudo
liberado, tenho uma regra para redirecionar o fluxo da porta 80 para 3128, e
com o tail eu vejo as linhas do access.log fluirem normalmente, mas somente
com TCP_MISS, tanto pra exe, imagens jpg, e tudo mais.
