    ## Include the Set-Cookie header if present.

    ## In order for Webauthn to work with multiple domains authentik must operate on a separate subdomain
    ## To use authentik on a separate subdomain:
    ##  * rename /config/nginx/proxy-confs/authentik.conf.sample to /config/nginx/proxy-confs/authentik.conf
    ##  * make sure that your dns has a cname set for authentik
    ##  * modify the $authentik_backend line below to set example.com to your domain
    ##  * restart the swag container
    set $authentik_backend authentik.example.com;

    return 302 https://$authentik_backend/authentik/?rd=$target_url;
}
