title: EhCache's CacheStatistics getCacheHits vs getInMemoryHits
body: <p>As specified in <a href="http://ehcache.org/apidocs/net/sf/ehcache/management/CacheStatistics.html" rel="nofollow">CacheStatistics</a>:</p>
  
  <ul>
  <li><p>getCacheHits():
  The number of times a requested item was found in the cache.</p></li>
  <li><p>getInMemoryHits(): 
  Number of times a requested item was found in the Memory Store.</p></li>
  </ul>
  
  <p>What actually is this memory store?  I had been thinking that "a cache" is a "in memory" instance in JVM as well?<br>
  What is the difference between cache and memory store in ehcache?  In what scenarios will the values returned be different?</p>
