====== Squid - Configure Squid ======

<WRAP important>
**WARNING:**  The refresh pattern on this config are **very aggressive** and sometimes a user will get old cached pages even for those sites which updates on daily basis,

if you face such issues, remove following directives from refresh pattern.

<code>	
ignore-reload override-expire ignore-no-cache ignore-no-store ignore-must-revalidate store-stale

# Cache Directory , modify it according to your system.
# but first create directory in root by
# mkdir /cache1
# chown proxy:proxy /cache1
# [for ubuntu user is proxy, in Fedora user is SQUID]
# I have set 100 GB for caching, Adjust it according to your need.
# My recommendation is to have one cache_dir per drive. zzz

# If you want to enable DATE time n SQUID Logs,use following
emulate_httpd_log on
logformat squid %tl %6tr %>a %Ss/%03Hs %<st %rm %ru %un %Sh/%<A %mt
log_fqdn off
 
# How much days to keep users access web logs
# You need to rotate your log files with a cron job. For example:
# 0 0 * * * /usr/local/squid/bin/squid -k rotate
