Please find below my configuration file for Squid Version 2.6.STABLE16. So I would need to add a cache_peer line to my conf: .... cache_peer 10.X.X.X parent 8080 0 default no-query no-digest no-netdb-exchange cache_peer 10.Y.Y.Y parent 8080 0 no-query no-digest no-netdb-exchange .... All the requests will go to 10.X.X.X unless it can't reach, am i correct to say that ? Thanks again, Josh squid.conf: -------------- http_port 8080 icp_port 0 cache_peer 10.X.X.X parent 8080 0 default no-query no-digest no-netdb-exchange hierarchy_stoplist cgi-bin ? acl QUERY urlpath_regex cgi-bin \? cache deny QUERY acl apache rep_header Server ^Apache broken_vary_encoding allow apache cache_mem 1536 MB cache_swap_low 90 cache_swap_high 95 maximum_object_size 4096 KB maximum_object_size_in_memory 50 KB cache_replacement_policy heap LFUDA memory_replacement_policy heap GDSF cache_dir aufs /usr/local/squid/cache 60000 16 256 access_log /usr/local/squid/logs/access.log squid hosts_file /etc/hosts refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 quick_abort_min 0 KB quick_abort_max 0 KB half_closed_clients off shutdown_lifetime 1 seconds acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 # https acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 8080 acl purge method PURGE acl CONNECT method CONNECT acl snmppublic snmp_community public acl corpnet dstdomain .corp.local http_access allow manager localhost http_access deny manager http_access allow purge localhost http_access deny purge http_access allow CONNECT SSL_ports http_access allow Safe_Ports http_access deny all httpd_suppress_version_string on visible_hostname proxy memory_pools off log_icp_queries off client_db off buffered_logs on never_direct deny corpnet never_direct allow all snmp_port 3401 snmp_access allow snmppublic snmp_access deny all snmp_incoming_address 127.0.0.1 coredump_dir /usr/local/squid/logs pipeline_prefetch on
