# to have these messages end up in /var/log/haproxy.log you will
# need to:
#
# 1) configure syslog to accept network log events. This is done
# by adding the '-r' option to the SYSLOGD_OPTIONS in
# /etc/sysconfig/syslog
#
# 2) configure local2 events to go to the /var/log/haproxy.log
# file. A line like the following can be added to
# /etc/sysconfig/syslog
#
# local2.* /var/log/haproxy.log
#

# This is an example VCL file for Varnish.

# It does not do anything by default, delegating control to the

# return statement.

# See the VCL chapters in the Users Guide at https://www.varnish-cache.org/docs/
# and for more examples.
# Marker to tell the VCL compiler that this VCL has been adapted to the
# new 4.0 format.
