# nginx-sso - example nginx config
#
# (c) 2015 by Johannes Gilger <heipei@hackvalue.de>
#
# This is an example config for using nginx with the nginx-sso cookie system.
# For simplicity, this config sets up two fictional vhosts that you can use to
# test against both components of the nginx-sso system: ssoauth & ssologin.
# In a real deployment, these vhosts would be separate hosts.

#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
