다음 명령으로 cache 목록 확인도 가능하다. (overflow는 큰 객체 사이즈만 저장되는 공간)

Map (session-storage): maps

두 명의 사용자가 Session.jsp 등을 실행하여 각기 세션을 만들면, size 명령을 통해서 객체 갯수 확인

CohQL 을 사용하는 것이 효율적으로 보이는데, HttpSession 객체의 value() 는 보여지지가 않는다.
원래 그러한지, 잘못된 테스트 방식인지 모르겠다.
우선 나중을 위해 정리하면

> ensure cache 'session-storage'

key() 는 잘나오나, value() 가 안나옴. 에러 debug log 를 보면 알려나?
사례도 ㄱ거의 없음. RFA 열어야 하나?
