How does Cloudflare's SSL/TLS configuration integrate with Nginx?

Cloudflare handles the SSL/TLS certificate management and encryption. Nginx acts as a reverse proxy, forwarding requests to your origin server. Cloudflare intercepts the traffic, applies the SSL/TLS encryption, and then forwards the encrypted traffic to your Nginx server. Nginx then decrypts the traffic and sends the response back to Cloudflare, which encrypts it again before delivering it to the client.
