Caddy Plugins
Caddy Plugins are modular extensions that enhance the functionality of Caddy, a modern, open-source web server written in Go. They allow developers to add features like authentication, caching, load balancing, and custom middleware without modifying the core server code. Plugins are typically written in Go and can be compiled directly into Caddy or loaded dynamically at runtime.
Developers should use Caddy Plugins when they need to extend Caddy's capabilities for specific use cases, such as adding HTTPS automation with Let's Encrypt, implementing security headers, or integrating with third-party services like Prometheus for monitoring. They are essential for customizing Caddy to handle complex web server requirements in production environments, such as API gateways or static site hosting with advanced features.
