Haproxy config file for SSL and basic authentication
# Haproxy config file for SSL and basic authentication
#
# Since ssl is needed, we need to use
# `make TARGET=linux26 USE_OPENSSL=1 ADDLIB=-lz` to install haproxy.
# Also, haproxy version must be haproxy-1.5-dev19 or above.
#
# An example curl command that queryies pic-collage.com/api/collages/feed is
# `curl -k -v -u 'collages:password' 'https://ec2-ip.compute-1.amazonaws.com/api/collages/feed'`
