How about the case when there are . or .. components in the absolute path part of an URL?
Including when those which are trailing without a slash.

E.g. Should http://example.org/users/joe and http://example.org/users/foo/../joe be the same?
What about http://alice.example.com/ vs http://alice.example.com/.
