#
# Example of NGINX as reverse-proxy terminating an HTTPS connection.
#
# This is not a complete NGINX config.
#
# Please refer to NGINX docs
#

# Note provided by Gabe R.: if you are using nginx as proxy server for Apache2
# make sure your nginx config DOES NOT contain the following
# -----
# location ~ /.well-known {
#  allow all;
#  }

# if X-Request-ID is set, NGINX will forward the same value to the next upstream
# if the header is not set, NGINX will generate a random request identifier and add it to the request.
#
# To guarantee backward compatibility, map to format the $request_id variable to a format that matches any old setups.
