http.realip - Caddy User Guide

http.realip
Plugin

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.
