Cloud CDN now treats HTTP responses with a max-age or s-maxage directive as cacheable, even if those responses do not have a Cache-Control

## Change Cloud CDN now treats HTTP responses with a **max-age** or **s-maxage** directive as cacheable, even if those responses do not have a **Cache-Control: public** directive. This allows Cloud CDN to cache additional responses and better align with HTTP standards. For details, see the [caching documentation](https://cloud.google.com/cdn/docs/caching#cache%5Fcontrol%5Fdirectives).
