MAPPING

Functions of this type should return a Subject (or a stream of them). Its path parts are URL-encoded and joined under a leading /, with any query parameters appended, to form the target subject.

The requesting peer should then additionally request on the returned path. If a stream is returned, then the remapping can be updated by emitting a second Subject, and the requesting peer will request on the new path, discarding the previously mapped path.

Note that the returned path will not pass through object-map or authentication module mappings before being requested.
