Cache-Control

Cache-Control is an essential HTTP header that dictates the caching policy for a resource. It contains directives (e.g., max-age, no-cache, no-store) that instruct browsers and intermediate caches (like CDNs) on whether, how, and for how long a response can be stored and reused. Dynamic e-commerce pages often have restrictive Cache-Control headers (like no-cache) that prevent traditional caching, which is a core problem that Speed Kit's Dynamic Caching is designed to solve.
