Subject MaxLifeSeconds and IdleTime definition
Date Mon, 16 Aug 2004 16:05:48 GMT
Hi,

I defined both MaxLifeSeconds and IdleTime in the cache.ccf file, but it does not work. Could
someone please tell me what I did wrong? Also, what the groupIDCache definition is used for?
Do I need it for simple memory cache without any auxiliary? 

I am new to JCS, and thanks in advance for your help!

Fang


My ccf file:
