  • for URL using the http or https, the scheme followed by '://', followed by the domain, followed by ':', followed by the port (the default port, 80 and 443 respectively, if explicitely specified);
  • for URL using file: scheme, the value is browser dependant;
  • for URL using the blob: scheme, the origin of the URL following blob:. E.g "blob:https://mozilla.org" will have "https://mozilla.org".
