Even though '..' may be valid in URIs for certain protocols, it would be
more reliable to resolve to a "true" absolute URI, such that
http://root.com/../foo becomes http://root.com/foo, and
http://root.com/foo/../bar becomes http://root.com/bar, etc. This may be
accomplishable with a simple regex: s|/[^/]+/\.\./|/|g on the path, with a
check for paths that are: /../etc
