- Do not cache data what maybe already has been cached (hibernate, oracle.. others??...)

- Be carefull with storing data in mem (caching) vs. cloning/clustering applications.

Just want to point out that for stateful data caching, cache aspect via AOP can be a great idea. But if we need caching mainly for entity data purpose, a good persistence layer (like Hibernate) also offers cache...]]> Wed, 20 Apr 2005 20:40:09 -0400 Wed, 20 Apr 2005 20:40:09 -0400 Wed, 20 Apr 2005 20:40:09 -0400 Apr 20, 2005 Ben Wang 1 Implementing Object Caching with AOP http://www.theserverside.com/discussions/thread.tss?thread_id=33382
