  2. 8.x drupal/core/vendor/symfony/http-foundation/Symfony/Component/HttpFoundation/Response.php \Symfony\Component\HttpFoundation\Response::getMaxAge()

Returns the number of seconds after the time specified in the response's Date header when the response should no longer be considered fresh.

First, it checks for a s-maxage directive, then a max-age directive, and then it falls back on an expires header. It returns null when no maximum age can be established.
