A Cache efficiently stores temporary objects primarily to improve an application's performance.
Shiro doesn't implement a full Cache mechanism itself, since that is outside the core competency of a Security framework. Instead, this interface provides an abstraction (wrapper) API on top of an underlying cache framework's cache instance (e.g. JCache, Ehcache, JCS, OSCache, JBossCache, TerraCotta, Coherence, GigaSpaces, etc, etc), allowing a Shiro user to configure any cache mechanism they choose.
