| - | >''httpd_accel_host virtual'': Squid comme un accélérateur de http((Dans ce mode, Squid est capable de se substituer à un serveur http, il fonctionne alors en "reverse proxying". Il ne sert donc plus à partager "le monde" pour un réseau, mais à partager une machine (ou plusieurs) "au monde". Ainsi, les clients n'accéderons plus au serveur http, mais à Squid. Dans une configuration classique, Squid devra donc écouter sur le port 80 et avoir connaissance du serveur http qu'il remplace. )) | ||
