When requesting / wol-proxy will show a loading page that polls /status every second. When the upstream server is ready the loading page will refresh causing the actual root page to be displayed
wol-proxy
wol-proxy automatically wakes up a suspended llama-swap server using Wake-on-LAN when requests are received.
When a request arrives and llama-swap is unavailable, wol-proxy sends a WOL packet and holds the request until the server becomes available. If the server doesn't respond within the timeout period (default: 60 seconds), the request is dropped.
This utility helps conserve energy by allowing GPU-heavy servers to remain suspended when idle, as they can consume hundreds of watts even when not actively processing requests.

API
GET /status - that's it. Everything else is proxied to the upstream server.
