Yeah, that is what should happen. We recently did it (disallow caching) for placement (http://specs.openstack.org/openstack/nova-specs/specs/queens/approved/placement-cache-headers.html) but it probably needs to be done just about everywhere else. I'd suggest you create a bug (probably just a nova one for now, but make it general enough that it is easy to add other projects) an perhaps that will help get some traction. -- Chris Dent (⊙＿⊙') https://anticdent.org/ freenode: cdent tw: @anticdent
