This capability is needed to enable the HTTP workflow task type. It enables the site controller to execute given http requests as part of Workflows that include tasks of type `ExtensionTaskWebhook`.

1. On the site controller edit the `docker-compose.yaml` file and append `HTTP_REQUEST=enabled` the following in the `environment` section of the `ms-tunnel` object like this:
```
  ...
  environment:
    - HTTP_REQUEST=enabled
```

2. Restart the site controller:
```
docker compose up -d
```
