It has always been my impression that only absolute URIs were allowed,
but then I had the same impression about the Referer: field and that one
seems to allow relative URIs (Why? It makes no sense to use relative there).

What would be the benefit of allowing relative URIs in a redirect?
I can imagine they would save space if there were a lot of vary sets,
but would that offset the cost of parsing? Perhaps. It certainly makes
more sense to have relative URIs here than it does for Referer.
