# Do not modify '/var/ipcop/proxy/squid.conf' directly since any changes
# you make will be overwritten whenever you resave proxy settings using the
# web interface! Instead, modify the file '/var/ipcop/proxy/acl' and then
# restart squid using the web interface. Changes made to the 'acl' file
# will propagate to the 'squid.conf' file at that time.
