Cache Control
In plain terms
An HTTP header directing how responses are cached.
Going deeper
The Cache-Control header tells browsers and proxies whether and how long to cache a response, balancing freshness and speed. It governs caching behavior.
Under the hood
Directives like max-age, no-cache, and private fine-tune caching; key to performance and correctness.
Examples
max-age, no-store, browser caching, CDN caching, performance tuning.
Think of it like...
Like instructions on perishable goods saying how long they can be stored.
