Parsing URLs

Parsing a URL is the process of taking a string and obtaining the URL record that - it represents. While this process is defined in URL, the HTML standard defines a - wrapper for convenience. URL

+ it represents. While this process is defined in URL, the HTML standard defines + several wrappers to abstract base URLs and encodings. URL

-

This wrapper is only useful when the character encoding for the URL parser has to - match that of the document or environment settings object for legacy reasons. When that is not the - case the URL parser can be used directly.

+

Most new APIs are to use parse a URL. Older APIs and HTML elements + might have reason to use encoding-parse a URL. When a + custom base URL is needed or no base URL is desired, the URL parser can of course be + used directly as well.
