Understand URL anatomy
An absolute URL can contain a scheme, authority, optional port, path, query string, and fragment. These parts have different escaping and routing meanings.
Inspect query parameters
Repeated parameter names remain separate ordered entries rather than being silently collapsed. Encoded values are decoded by the browser URL standard.
Handle credentials carefully
If user information appears in the authority, the parser reports its presence without displaying the username or password in the results table.
Parsing is not navigation
No DNS, HTTP, reputation, availability, redirect, or destination request occurs.
Review before reusing a URL
Check origin, path segments, parameters, and fragment separately before copying data into an application.
