Restore Real IP Address From Cloudflare CDN in Nginx

Cyrus Kao

Cloudflare CDN works just like a reverse proxy, it sits in front of your web servers and forwards client requests to them. So the requests reaching your server actually came from Cloudflare. To restore the original client's IP address, we'll be using ngx_http_realip_module in Nginx to retrieve them from headers.
