    # Optional: Rate limiting
    # Note: Rate limiting in Caddy requires a plugin or external middleware
    # For built-in rate limiting, consider using:
    # 1. Caddy rate-limit plugin: https://github.com/mholt/caddy-ratelimit
    # 2. External rate limiting service
    # 3. Nginx as described in docs/reverse-proxy.md
}

# For local development without a domain (comment out the above and use this instead)
# localhost {
#     reverse_proxy gpt4free:8080
