What it says
On cancelRequest for a request still running, the host stops its work where it can (an http, upload or loadImage download's URLSession task is cancelled) and still answers it exactly once, failed if the work was stopped, at once if its handler had not started; a cancelled loadImage leaves the image store as it was; a cancel of an id already answered or never requested does nothing.
