about: URLs

about: URLs server as identifier, potentially with an associated resource. The identifier is given in the URL's scheme data.

Identifier Resource Notes
"blank" A resource whose Content-Type is text/html;charset=utf-8 and entity body is the empty string.
"invalid" - Used to represent a network error.
"legacy-compat" - Used in HTML for XSLT serializers.
"unicorn" A resource whose Content-Type is image/svg+xml and entity body is the contents of unicorn.svg. Unicorn!

To obtain a resource from an about: URL, run these steps:

  • If URL's scheme data is not the literal string "about" or "invalid", return a network error. (URL's query is simply not taken into account and can be anything.)
  • Return the resource corresponding to the identifier as listed in the table above, with HTTP status code 200 and HTTP status text "OK".
