The live Caddy was returning a blank page (NOP, status 0) because its site block had no responder \u2014 no reverse_proxy to the blog. This adds a known-good HTTP-only Caddyfile matching the actual topology (Cloudflare terminates TLS -> Caddy :80 -> SWS blog:80): - reverse_proxy blog:80 (the missing responder that caused the blank page) - encode zstd gzip (fixes: origin was serving everything uncompressed) - security headers (fixes: HSTS/X-Frame-Options/etc were absent) - trusted_proxies + client_ip_headers for correct Cloudflare visitor IPs - http:// scheme so Caddy does not try to provision TLS (Cloudflare does) Validated + fmt-clean against the caddy-cf image; tested end-to-end locally (Caddy -> SWS) returning HTTP 200 with gzip and headers.

# Topology: Cloudflare (terminates TLS) -> Caddy (HTTP :80) -> SWS (blog:80)

# Cloudflare handles the public HTTPS cert, so Caddy serves plain HTTP on :80
|
|
# and does NOT need the Cloudflare DNS-01 / automatic-HTTPS setup. Set the
|
|
# Cloudflare SSL/TLS mode to "Full" so CF->origin is encrypted at the network
|
|
# layer (e.g. over your tunnel/Netbird), even though this listener is HTTP.

|
# Copy this file to /etc/caddy/Caddyfile on the caddy_cf host and reload:

# docker exec caddy_cf caddy reload --config /etc/caddy/Caddyfile

|
# or restart the container.
