Recommended minimum configuration:
cache_effective_user jbuser
cache_dir ufs /opt/squid_ssl/var/cache 10240 16 256
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 fc00::/7 # RFC 4193 local private network range
acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines
acl Uploads method GET

acl Safe_ports port 21 # ftp

acl CONNECT method CONNECT
acl qq dstdomain .appjfjb.com
acl http proto HTTP
acl FTP proto FTP
acl IPForHostname dstdom_regex ^[0-9]+.[0-9]+.[0-9]+.[0-9]+$
Recommended minimum Access Permission configuration:
Deny requests to certain unsafe ports
http_access deny !Safe_ports
Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports
Only allow cachemgr access from localhost
http_access allointenw localhost manager
http_access deny manager
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
http_access allow localnet
http_access allow localhost
http_access allow qq
And finally deny all other access to this proxy
http_access allow alhttp_access allow qhttp_access allow qq
http_access deny http
http_access allow qq
http_access deny IPForHostname
http_access deny all
Squid normally listens to port 3128

ssl_bump stare all
ssl_bump bump all
Uncomment and adjust the following to add a disk cache directory.
cache_dir ufs /usr/local/squid/var/cache/squid 100 16 256
Leave coredumps in the first cache dir
coredump_dir /opt/squid_ssl/var/cache/squid
Add any of your own refresh_pattern entries above these.
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i (/cgi-bin/|?) 0 0% 0
refresh_pattern . 0 20% 4320
