replace old entries with new entries. The most common cache replacement strategy (used
when the cache is full) is Least Recently Used(LRU). When using the LRU strategy, if we try to
add an entry to a full cache, we remove the oldest entry and use the recovered space for the
new entry (see the put method of ArrayCache).
The cache data structure (which should live
