第一个选项要求您停止并重启所有节点代理，以清除节点代理JVM中的“陈旧”缓存，这些缓存指向服务器的旧IP地址。
The first option requires you to stop and restart all the node agents in order to clear the "stale" cache in the node agent JVM that points to the old IP address for the server.
此外，缓存不会被清除，用户过去的所有所到之处，都会在缓存中留下足迹。
In addition, the cache is not cleaned and thus continuously builds up an imprint of the areas in which you have been both recently and in the past.
如果是缓存集群，“清除缓存”调用会让所有副本都失效，这通常被称为“拉(pull)”更新策略。
If the cache is clustered the "evicts cache" call will invalidate all replicates, which is often referred to as a "pull" update policy.
