http_access deny situs
http_allow localnet
http_allow all
http_port 3128 transparent
cache_mem 8 mb
memory_replacement_policy heap GDFS
cache_replacement_policy heap LFUDA
store_dir_select_algorithm round-robin
cache_dir aufs /cache 10000 24 256
cache_store_log none
cache_access_log /var/log/squid/access.log
cache_effective_user proxy
cache_effective_group proxy
