Nobody else has access to that cache, so "public" can't mean anything.

Maybe.  Or maybe s-maxage crept in because of some memory trashing on the
server side.  Once you see that the server is buggy, you can't be sure what
it wants.

is only a valid question if he is sane.  He may be doing it because the
