I don't really know what will be the behavior from the Apache with this config : - Pragma/Cache-Management has a similar part so you provide them with 2 differents configs. It is weird. - no-keep signify which the ressource should not be cached. So how can it be revalidated ? https://socialexpresions.com/story6553857/%E4%BB%AE%E6%83%B3%E9%80%9A%E8%B2%A8-%E3%82%AB%E3%82%B8%E3%83%8E-%E3%82%B3%E3%82%A4%E3%83%B3-an-overview
