Class ResponseCache

java.lang.Object

com.djrapitops.plan.system.webserver.cache.ResponseCache

public class ResponseCache
extends java.lang.Object

This class contains the page cache.

It caches all Responses with their matching identifiers. This reduces CPU cycles and the time to wait for loading the pages. This is especially useful in situations where multiple clients are accessing the server.
