I’ve spent 3 months perfecting the cache capabilities of my squid cache proxy and come up with the following…although I occasionally still have some problems with http11 support this configuration has performed optimally for me. I have a 75 gig hard drive and a 2.66 celeron processor operating on opensuse 12.2

# Recommended minimum configuration:
#
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
# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
acl localnet src 10.0.0.0/8 # RFC1918 possible internal network
acl localnet src 172.16.0.0/12 # RFC1918 possible internal network
acl localnet src 192.168.0.0/16 # RFC1918 possible internal network
acl localnet src fc00::/7 # RFC 4193 local private network range
acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines
acl Safe_ports port 1-65535
acl CONNECT method GET POST HEAD CONNECT PUT DELETE # http
#
# Recommended minimum Access Permission configuration:
#
# Only allow cachemgr access from localhost
http_access allow all
# Deny requests to certain unsafe ports
# Deny CONNECT to other than secure SSL ports
# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only
# one who can access services on “localhost” is a local user
#http_access deny to_localhost
#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#
# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
# allow localhost always proxy functionality
# And finally deny all other access to this proxy
# Squid normally listens to port 3128
http_port 8080 transparent
# We recommend you to use at least the following line.
hierarchy_stoplist cgi-bin ?
# Uncomment and adjust the following to add a disk cache directory.
cache_dir ufs /var/cache/squid 32768 36 256
# Leave coredumps in the first cache dir
coredump_dir /var/cache/squid
# Add any of your own refresh_pattern entries above these.
