Char-by-char equivalence is too weak for URIs.

RFC 2396 resolution tells us how to convert relative URIs to absolute,
which can then be compared char-by-char.

Server-level equivalence (accessing the resource entity and seeing if you
get the same bytes) is inherently hopeless, as the entity contents may
literally change from second to second.
