Abstract

The immutable HTTP response Cache-Control extension allows servers to identify resources that will not be updated during their freshness lifetime. This ensures that a client never needs to revalidate a cached fresh resource to be certain it has not been modified.


For the definition of Status, see RFC 2026.

For the definition of Stream, see RFC 4844.
