What is the use of cache in http?

In HTTP, cache mechanisms are implicit directives to caches where expiration times and validators are specified by the server. For this purpose, we use the Cache-Control header. The Cache-Control header is used to allow the client or the server to transmit a variety of directive in either request or response. [9]

How does a cache work? The flow of requests starts with a cache miss (empty cache outcome). On its way back, the cache would read caching instructions and store the response. All subsequent requests for this particular resource would yield to cache hits, until the resource becomes stale and needs to be revalidated. [2]

Just so, What is an example of a cache request? For example: The following cache request directives can be used by the client in its HTTP request: A cache must not use the response to satisfy a subsequent request without successful revalidation with the origin server.
