It's the result of all redirects. If the spec doesn't say this then it
should, as it's pretty fundamental.

The canonical form slash addition only applies for a completely empty path:
http://domain.com
becomes
http://domain.com/

...because a HTTP URL with no path component is invalid, so you can't
actually request the former in order to get redirected to the latter.

Other than that (and adding http://, of course) the rest of the
canonicalisation is handled by HTTP redirects.
