HAproxy virtual site load balancing
# This configuration use acl's to distinguish between url's passwd and then route
# them to the right backend servers. For the backend servers to handle it correctly, you
# need to setup virtual hosting there as well, on whatever you use, tomcat, nginx, apache, etc.
# For this to work with SSL, put pound before HAproxy and use a configuration file similar to
# https://gist.github.com/1984822 to get it working
