haproxy/examples/content-sw-sample.cfg

#
# This is a sample configuration. It illustrates how to separate static objects
# traffic from dynamic traffic, and how to dynamically regulate the server load.
#
# 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 deliver the stats page.
