| Token           | Description                                                              |
| --------------- | ------------------------------------------------------------------------ |
| `::CLIENT_IP::` | The visitor's IP address.                                                |
| `::RAY_ID::`    | A unique identifier given to every request that goes through Cloudflare. |
