Class CacheStrategy

java.lang.Object

org.aoju.bus.http.cache.CacheStrategy

public final class CacheStrategy
extends Object

Given a request and cached response, this figures out 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:

JDK 1.8+

Version:

3.6.6
