# PROVIDE: squid
|
|
# REQUIRE: LOGIN
|
|
# KEYWORD: shutdown
|
|
#
|
|
# Note:
|
|
# Set "squid_enable=yes" in either /etc/rc.conf, /etc/rc.conf.local or
|
|
# /etc/rc.conf.d/squid to activate Squid.
|
|
#
|
|
# Additional variables you can define in one of these files:
|
|
#
|
|
# squid_chdir: the directory into which the rc system moves into before
|
|
# starting Squid. Default: /var/squid
|
|
#
|
|
# squid_conf: The configuration file that Squid should use.
|
|
# Default: %%PREFIX%%/etc/squid/squid.conf
|
|
#
|
|
# squid_fib: The alternative routing table id that Squid should use.
|
|
# Default: none
|
|
# See setfib(1) for further details. Note that the setfib(2)
|
|
# system call is not available in FreeBSD versions prior to 7.1.
|
|
#
|
|
# squid_user: The user id that should be used to run the Squid master
|
|
# process. Default: squid.
|
|
# Note that you probably need to define "squid_user=root" if
|
|
# you want to run Squid in reverse proxy setups or if you want
|
|
# Squid to listen on a "privileged" port < 1024.
|
|
#
|
|
# squid_pidfile:
|
|
# The name (including the full path) of the Squid
|
|
# master process' PID file.
|
|
# Default: /var/run/squid/squid.pid.
|
|
# You only need to change this if you changed the
|
|
# corresponding entry in your Squid configuration.
|
|
#
|
|
# squid_flags: Additional commandline arguments for Squid you might want to
|
|
# use. See squid(8) for further details.
|
|
#
|
|
# squid_krb5_ktname:
|
|
# Alternative Kerberos 5 Key Table.
|
|
# Default: none
|
