They may not raise errors on inputs that other applications consider ++invalid. They may also succeed on some inputs that might not be considered ++URLs elsewhere. Their purpose is for practical functionality rather than ++purity. ++ ++Instead of raising an exception on unusual input, they may instead return some ++component parts as empty strings. Or components may contain more than perhaps ++they should. ++ ++We recommend that users of these APIs where the values may be used anywhere ++with security implications code defensively. Do some verification within your ++code before trusting a returned component part. Does that ``scheme`` make ++sense? Is that a sensible ``path``? Is there anything strange about that ++``hostname``? etc. ++ ++What constitutes a URL is not universally well defined. Different applications ++have different needs and desired constraints. For instance the living `WHATWG ++spec`_ describes what user facing web clients such as a web browser require. ++While :rfc:`3986` is more general. These functions incorporate some aspects of ++both, but cannot be claimed compliant with either.
