+# Caddy Fallback Server
+
+This directory contains the `docker-compose.yml` for running a standalone Caddy server, potentially as a fallback or for specific local proxy needs.
+
+## Running with Podman Compose
+
+To run this service using `podman-compose`:
+
+1.  Navigate to this directory:
+    ```bash
+    cd optimized/standalone/Caddy
+    ```
+2.  Ensure `Caddyfile` and `maintenance.html` exist in this directory as they are mounted as volumes.
+3.  Start the service:
+    ```bash
+    podman-compose up -d
+    ```
+
+## Running with Podman
+
+You can run the Caddy service directly with Podman. Note that for proper function, the `Caddyfile`, `maintenance.html`, and volume mounts are crucial.
+
+```bash
+podman run -d \
+  --name caddy_fallback \
+  --restart unless-stopped \
+  -p "8080:80" \
+  -p "8443:443" \
+  -v ./Caddyfile:/etc/caddy/Caddyfile \
+  -v ./maintenance.html:/srv/maintenance/maintenance.html \
+  -v caddy_data:/data \
+  -v caddy_config:/config \
+  -v caddy_logs:/var/log/caddy \
+  caddy:latest
+```
+
+## Notes
+
+*   Ensure the `Caddyfile` and `maintenance.html` are configured correctly for your use case.
+*   The Caddy service was categorized as `standalone` because Traefik is designated for Swarm ingress, implying Caddy has a specialized, non-Swarm role here.
