The agent and cache are completely independent. So you have two copies of each article on your harddisk. In anticipation of the next question, the agent and cache were designed this way deliberately.

Do you think caching adn agentizing in the same time, a recommended/safe practice ? Oh, and given the fact I am caching ticked/dormant and even unread articles, can I safely enable agent expiration on my groups ? If I understand correctly, caching prevent me from a server expiration and adjusting in this case 2 or 3 more variables I can still keep a copy of some articles locally (no expiration can apply).

(cache ?, agent ?, > randomly ?). It's deterministic; it should prefer the cache. The actual logic is recursive and, at times, obscure so some functions may check the agent first. >> In anticipation of the next question, the agent and cache were >> designed this way deliberately. > > No problem with how this was done ;) just a question.

Very good, you found the primary justification for keeping the cache and agent separate. Agent expiration only applies to the agent's folders so your cached articles can NOT be expired. Note: An article that is both cached and agentized may, by expiration, end up only cached. I'm not sure about your 'server expiration' comment. My interest has largely been the agent.
