I have a cache model set up like this:

    <cacheModel id="FindAllCache" implementation="LRU" readOnly="false">
      <flushInterval minutes="5"/>
      <property name="CacheSize" value="2"/>
    </cacheModel>

    <select id="FindAll" extends="Base" resultMap="Result" cacheModel="FindAllCache">
    </select>

I have turned on iBATIS logging.  When I execute the select statement more than once within one session, the logs say that there is a cache miss each time.

How do I get a read/write (per session) cache to work?
