#
# 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_group: The group id that should be used to run the Squid master
# process. Default: squid
# Note that it affects squid pid dir also, where SHM files
# may be stored on some OS (see r391555)
#
# squid_maxwait: Seconds to wait for squid PID file
# Default: 10
#
# 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
# squid_krb5_config:
# Alternative Kerberos 5 config file
# Default: none
