Class CacheStrategy

org.miaixz.bus.http.cache.CacheStrategy

public class CacheStrategy
extends Object

Given a request and a cached response, this class determines whether to use the network, the cache, or both. Selecting a cache strategy may add conditions to the request (like the "If-Modified-Since" header for conditional GETs) or warnings to the cached response (if the cached data is potentially stale).

Since:
