http.realip Plugin

This feature does not come with Caddy by default. To get it, select the http.realip plugin when you download Caddy.

This plugin allows you to see the actual client IP from X-Forwarded-For headers if you are running behind a CDN or Proxy. It will make it so logs and other downstream directives will see the actual client IP, not the proxy's. Implements security measures so that X-Forwarded-For cannot be spoofed from unauthorized IP ranges.
