Squid Caching Server

(... explain what we want to get our of squid ... Basic proxy ... proxy forwarded to remote proxy .... reverse proxy ... more words here....)

Why is this taking so long ???

"I installed squid3 (on Ubuntu), but looking at the configuration file, I am lost. I tried googling but it looks all too complicated." -- stack overflow user

Squid is a monster. Years of development and added features have created a configuration file that has 8000 lines of comments and 20 actual lines of configuration which need to be modified for it to work at all.

basic proxy configuration

The configuration below can be found on the squid containers on both basement servers (Joey and DeeDee). To use this server set your web browser proxy to the http_port in the configuration file (3128).

acl SSL_ports port 443
acl Safe_ports port 80          # http
acl Safe_ports port 21          # ftp
acl Safe_ports port 443         # https
acl Safe_ports port 70          # gopher
acl Safe_ports port 210         # wais
acl Safe_ports port 1025-65535  # unregistered ports
acl Safe_ports port 280         # http-mgmt
acl Safe_ports port 488         # gss-http
acl Safe_ports port 591         # filemaker
acl Safe_ports port 777         # multiling http
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow localhost manager
http_access deny manager
http_access allow localhost
acl my_internal_net src
http_access allow my_internal_net
http_port 3128
coredump_dir /var/spool/squid
refresh_pattern ^ftp:           1440    20%     10080
refresh_pattern ^gopher:        1440    0%      1440
refresh_pattern -i (/cgi-bin/|\?) 0     0%      0
refresh_pattern (Release|Packages(.gz)*)$      0       20%     2880
refresh_pattern .               0       20%     4320

reverse proxy configuration

Work in progress.

minimal (no ssl) configuration

With an ssh tunnel set from our local static web server coming onto the server ( at port 8085 we tell squid to route all traffic on port 80 to the server on the other end of the tunnel.

debug_options ALL,2 28,9
http_port 80 accel no-vhost
cache_peer parent 8085 0 no-query originserver name=corbin
acl theworld src all
acl our_sites dstdomain all
http_access allow theworld
http_access allow our_sites
cache_peer_access corbin allow our_sites
cache_peer_access corbin allow theworld
http_access deny all

Secure reverse proxy

... working on it ...

From: squid example configurations

https_port 443 accel \
  cert=/etc/ssl/certs/ssl-cert-snakeoil.pem \

# First (HTTP) peer
cache_peer parent 8086 0 no-query originserver login=PASS name=lilly

acl pdx dstdomain
cache_peer_access lilly allow pdx
http_access allow pdx

# Security block for non-hosted sites
http_access deny all


acl PORT80 myport 80
http_access deny PORT80 pdx
deny_info 301: pdx

Dual Proxy Configuration

TODO: Having a local proxy combined with a "pihole" dns server seems to improve browsing performance considerably. Adding a second proxy upstream would allow less location based garbage as well. [ TaskDualProxyConfiguration Dual Proxy Configuration Notes]
