| * This demonstrates the most minimal http server you can make with lws, |
| * with an added websocket proxy distributing what is received on a |
| * dumb-increment wss connection to https://libwebsockets.org to all |
| * browsers connected to this server. |
| * |
| * To keep it simple, it serves stuff in the subdirectory "./mount-origin" of |
| * the directory it was started in. |
| * You can change that by changing mount.origin. |
