I'm sorry, but the provided knowledge sources do not contain any examples or information about using Ory Oathkeeper with Caddy. However, Ory Oathkeeper can be integrated with various systems and proxies. For instance, there's an example of integrating Ory Oathkeeper with Traefik, a modern HTTP proxy and load balancer for microservices, via the ForwardAuth Middleware and Access Control Decision API [source](
https://www.ory.sh/docs/oathkeeper/guides/traefik-proxy-integration). For specific guidance on using Ory Oathkeeper with Caddy, I would recommend checking the official Ory documentation or community resources.
