Connect Client
Your client connects via WebSocket to the tunnel server and receives a unique tunnel ID.
Public Request
HTTP requests arrive at your public URL (e.g., https://abc123.tunnel.eldrin.io) and are forwarded to your client.
Local Processing
Your client processes the request locally and sends the response back through the secure tunnel.
