# Config ideal for load balancing many back-end Virtual Hosts with a pair of load balancers (one is for fail-over).

# HAProxy's ACL is ideal for dedicating more resources to certain virtual hosts especially to handle traffic spikes.

# Reference: 
# http://www.techrawr.com/2009/09/18/using-the-acl-in-haproxy-for-load-balancing-named-virtual-hosts

# Don't copy blindly, change to suit your needs; at a minimum:-
# change maxconn based on your back-end server(s) capabilities
# enable/disable cookie option - disable if you don't want sticky sessions
