URL
Parser

Protocol/scheme, username, password, host, port, pathname, search/query string (as parsed key-value pairs), and hash/fragment are all extracted and displayed separately.

Yes. Query strings with multiple parameters, encoded characters, and repeated keys are all correctly parsed into an organised list.

Yes. URLs containing username:password@ credentials (rare in modern web apps but common in connection strings) are correctly parsed.

The parser is designed for absolute URLs (those starting with http://, https://, ftp://, etc.). Relative URLs may not parse correctly without a base URL.

Data URIs (data:text/html;base64,...) have a different structure from standard URLs. The parser extracts the protocol as 'data' and the remainder as the path.
