 You are responsible for providing a suitable `location` block in your override file as required for your service. By default, `nginx-proxy` uses the `VIRTUAL_HOST` name as the upstream name for your application's Docker container; see [here](#unhashed-vs-sha1-upstream-names) for details. As an example, if your container has a `VIRTUAL_HOST` value of `app.example.com`, then to override the location block for `/` you would create a file named `/etc/nginx/vhost.d/app.example.com_location_override` that contains something like this:
