Description

This policy controls if a page with Cache-Control: no-store header can be stored in back/forward cache. The website setting this header doesn't expect the page to be restored from back/forward cache since some sensitive information could still be displayed after the restoration even if it's no longer accessible.

If you enable or don't configure this policy, the page with Cache-Control: no-store header might be restored from back/forward cache unless the cache eviction is triggered (for example, when there's HTTP-only cookie change to the site).
