proxy_cache_min_uses

Описание

`proxy_cache_min_uses` defines how many times a cached response must be served from the cache before it is deemed valid and can be effectively reused for subsequent client requests. This is particularly useful in scenarios where responses are pre-cached from upstream servers but may require a certain threshold for usability based on characteristics like cache hit rates or load balancing designs. If the cached response has been served fewer times than the specified minimum uses, requests for that content will bypass the cached version, potentially fetching a fresh copy from the upstream server instead. This directive is applicable in various contexts, including `http`, `server`, and `location`, allowing flexible application in different parts of the NGINX configuration. The directive accepts a single integer argument that represents the minimum use threshold. By optimizing the usage threshold, administrators can control cache efficiency and manage server load better, mitigating scenarios that could lead to stale or less reliable content being served from cache.
