CacheControldirektiv
CacheControldirektiv refers to directives or instructions used to manage how web resources are cached. These directives are typically implemented using HTTP headers or meta tags within a web page's HTML. Their primary purpose is to influence the behavior of browsers, proxy servers, and Content Delivery Networks (CDNs) in storing and serving cached copies of web content, thereby optimizing performance and controlling data freshness.
Common CacheControldirektiv include Cache-Control, Expires, and Pragma headers. The Cache-Control header is the most powerful and
The Expires header provides a specific date and time after which a cached response is considered stale.
