<DL>
<DD>Maintain the number of cache hits and misses. A cache hit occurs every
 time the get method is called and the cache contains the requested
 object. A cache miss represents the opposite occurence.<p>

 Keeping track of cache hits and misses lets one measure how efficient
 the cache is; the higher the percentage of hits, the more efficient.
