Cache-Control
An HTTP header that specifies caching directives for requests and responses. Common directives include max-age (seconds until stale), no-cache (must revalidate), no-store (never cache), public (cacheable by any cache), and private (only cacheable by the browser). Proper cache-control is essential for performance and preventing stale content. Related status codes include 304 Not Modified.
