Class NullCacheProvider

java.lang.Object
  m.c.m.proxyma.plugins.caches.NullCacheProvider

All Implemented Interfaces:

CacheProvider

public class NullCacheProvider
extends java.lang.Object
implements CacheProvider

This is a null implementation of the interface CacheProvider. It doesn't stores anything and never returns anything.
IMPORTANT: The cache plugn is used 2 times into the engine:

• After the last preprocessor-plugin has run. In this way the engine can evaulate if there is a cached version of the response already available.
• Before start the the serializer-plugin to decide if the resource can be cached.
