# This is a sample configuration

# It listens on 192.168.1.10:80, and directs all requests for Host 'img' or
# URIs starting with /img or /css to a dedicated group of servers. URIs
# starting with /admin/stats are directed to a backend dedicated to statistics.
# TCP splicing is used on static objects to relieve the process from the heavy
# job.
