# WELCOME TO SQUID DEB PROXY

#
# This config file is a version of a squid proxy file optimized
# as a configuration for a caching proxy for Ubuntu systems.

# http://www.squid-cache.org/ and in the FAQ
# settings that you may want to customize
# ---------------------------------------
# this file contains private networks (10.0.0.0/8, 172.16.0.0/12,
# 192.168.0.0/16) by default, you can add/remove additional allowed
# source networks in it to customize it for your setup
acl allowed_networks src "/etc/squid-deb-proxy/autogenerated/allowed-networks-src.acl"
# this file contains the *archive.ubuntu.com mirrors by default,
# if you use a different mirror, add it there
acl to_ubuntu_mirrors dstdomain "/etc/squid-deb-proxy/autogenerated/mirror-dstdomain.acl"
# this contains the package blacklist
acl blockedpkgs urlpath_regex "/etc/squid-deb-proxy/autogenerated/pkg-blacklist-regexp.acl"
