Eu configurei um cache de squid em um roteador 3G / wifi portátil que eu criei.
O proxy funciona, mas eu só vejo TCP_MISS, com um muito raro TCP_MEM_HIT
Eu nunca tentei isso antes, e este é o arquivo de configuração que eu criei:
acl manager proto cache_object
acl localhost src 127.0.0.1/32 ::1
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1
acl localnet src 192.168.99.0/24
acl SSL_ports port 443
acl Safe_ports port 80
acl Safe_ports port 21
acl Safe_ports port 443
acl Safe_ports port 70
acl Safe_ports port 210
acl Safe_ports port 1025-65535
acl Safe_ports port 280
acl Safe_ports port 488
acl Safe_ports port 591
acl Safe_ports port 777
acl CONNECT method CONNECT
http_access allow manager
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow localnet
http_access allow localhost
http_access deny all
http_port 3128

refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern . 0 20% 4320
cache_mgr *******@*****.com
Mesmo os arquivos provenientes das páginas http embutidas do dispositivo 3G não armazenam em cache.
Eu cometi algum erro no arquivo de configuração?
Existe alguma maneira especial de configurar / var / spool / squid3? Acabei de usar o sudo mkdir / var / spool / squid3 e ele criou todos os bits dentro.
Aqui está a saída do cache.log:

Aqui está um par de linhas de access.log

Duas máquinas diferentes, o mesmo arquivo, duas falhas
Mais duas linhas, estas são estranhas:

O que é 1.2.3.9? como upload.wikimedia.org pode estar no meio desse URL? Isso é algum tipo de outro cache mantido pela T-Mobile entre nós e o resto da 'net?
