## Tested and working on squid 3.3.10-r0 and Alpine 2.7.1 (kernel 3.10.19-0-grsec), 64-bit

## 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 192.168.2.0/24 # RFC1918 possible internal network
|
|
## Allow anyone to use the proxy (you should lock this down to client networks only!):
|
|
# acl localnet src all
|
|
## IPv6 local addresses:
|
|
acl localnet src fc00::/7 # RFC 4193 local private network range
|
|
acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines

## Prevent caching jsp, cgi-bin etc
|
|
cache deny QUERY
|
|
|
|
## Only allow access to the defined safe ports whitelist
|
|
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 allow 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
|
|
|
|
## And finally deny all other access to this proxy
|
|
http_access deny all
|
|
|
|
## Squid normally listens to port 3128
|
|
http_port 3128
|
|
## If you have multiple interfaces you can specify to listen on one IP like this:
|
|
#http_port 1.2.3.4:3128
|
|
|
|
## Uncomment and adjust the following to add a disk cache directory.
|
|
## 1024 is the disk space to use for cache in MB, adjust as you see fit!
|
|
## Default is no disk cache
|
|
#cache_dir ufs /var/cache/squid 1024 16 256
|
|
## Better, use 'aufs' cache type, see
|
|
##http://www.squid-cache.org/Doc/config/cache_dir/ for info.
|
|
cache_dir aufs /var/spool/squid 10240 16 256
|
|
## Recommended to only change cache type when squid is stopped, and use 'squid -z' to
|
|
## ensure cache is (re)created correctly
|
|
|
|
## Leave coredumps in the first cache dir
|
|
#coredump_dir /var/cache/squid
|
|
|
|
## Where does Squid log to?
|
|
access_log /var/log/squid/access.log
|
|
## Use the below to turn off access logging
|
|
#access_log none
|
|
## When logging, web auditors want to see the full uri, even with the query terms
|
|
#strip_query_terms off
|
|
## Keep 7 days of logs
|
|
#logfile_rotate 7
|
|
|
|
## How much RAM, in MB, to use for cache? Default since squid 3.1 is 256 MB
|
|
cache_mem 64 MB
|
|
|
|
## Maximum size of individual objects to store in cache
|
|
maximum_object_size 1 MB
|
|
|
|
## Amount of data to buffer from server to client
|
|
read_ahead_gap 64 KB
|
|
|
|
## Use X-Forwarded-For header?
|
|
## Some consider this a privacy/security risk so it is often disabled
|
|
## However it can be useful to identify misbehaving/problematic clients
|
|
#forwarded_for on
|
|
forwarded_for delete
|
|
|
|
## Suppress sending squid version information
|
|
httpd_suppress_version_string on
|
|
|
|
## How long to wait when shutting down squid
|
|
shutdown_lifetime 30 seconds
|
|
|
|
## Replace the User Agent header. Be sure to deny the header first, then replace it :)
|
|
#request_header_access User-Agent deny all
|
|
#request_header_replace User-Agent Mozilla/5.0 (Windows; MSIE 9.0; Windows NT 9.0; en-US)
|
|
|
|
## What hostname to display? (defaults to system hostname)
|
|
#visible_hostname a_proxy
|
|
|
|
## Use a different hosts file?
|
|
#hosts_file /path/to/file
|
|
|
|
