 * `no-transform` — Indicates that an intermediary — regardless of whether it implements a cache — must not transform the payload.
-* `vary` — Cloudflare does not consider vary values in caching decisions. Nevertheless, vary values are respected when [Vary for images](/cache/advanced-configuration/vary-for-images/) is configured and when the vary `cache-control` header is [`vary: accept-encoding`](/speed/optimization/content/compression/).

 * `immutable` — Indicates to clients the response body does not change over time. The resource, if unexpired, is unchanged on the server.
