Caddy Reverse Proxy

The Caddy Reverse Proxy is a powerful, secure, and easy-to-configure solution for managing web traffic between users and backend servers. Acting as an intermediary, the Caddy Reverse Proxy forwards client requests to backend servers, providing benefits like SSL termination, load balancing, and enhanced security. Designed for flexibility and performance, Caddy automates HTTPS setup, making it ideal for developers and organizations needing a reliable reverse proxy solution.
