Global settings

#---------------------------------------------------------------------
global
# 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
#
log 127.0.0.1 local2

chroot      /var/lib/haproxy
pidfile     /var/run/haproxy.pid
maxconn     4000

For sample if this is my config where do I need to set headers ??

Woops, I guess I didn't receive a notification on your comments @GitAlik, these go in the frontend-ideally after your bind but before your ACLs (at least, that's how I organize them).
