📚 About Proxy Headers
• REMOTE_ADDR: IP of the TCP connection (a proxy IP if behind a proxy)
• X-Forwarded-For: Original client IP added by proxies (comma-separated chain)
• CF-Connecting-IP: Real client IP set by Cloudflare
• X-Forwarded-For from untrusted sources can be spoofed — production code must validate against a trusted proxy list.
