# Installed as /etc/nginx/conf.d/00-cloudflare-real-ip.conf on the first server.
#
# Cloudflare proxies the Progmasoft, Tala and Tazel hosts, so the peer of
# Nginx is a Cloudflare edge, and each request may come from another edge.
# Without this file the address the API rate-limits by is that edge: the
# sign-in limit then never fills for one visitor and is shared by unrelated
# ones. A connection from a Cloudflare range takes the visitor from
# CF-Connecting-IP; any other peer keeps its own address, so the header cannot
# be forged by a direct connection to the server. The ranges are those of
# https://www.cloudflare.com/ips/ (checked 2026-11-09).
