 When content varies on user account the content is "private" and should
 be marked as such in Cache-Control.

 When content is not supposed to be stored by caches it need to be
 marked "no-store"

 "no-cache" is a slightly fuzzy middle ground which is treated
 differently by all browsers and caches. As well as differently when sent
 on request and response. It is allowed to be stored and shared around,
 but has to be revalidated with the origin before use.

 Interesting results. Thank you for mentioning this problem.

 Using "private" or "no-store" as appropriate for your content should
 fix this problem for all browsers.
