Hi, I am newbie to squid. Recently, we have installed squid with two cache dir of 25GB. A few questions: 1. Is there some sort of parameters to set for objects in the cache to expire so that they get overwritten by recent objects and also to ensure the disk will not be 100% full? 2.How I can purge the cache, automatically i.e when the cache reaches 80%, . Netscape Suitesopt has that features. 3. How does and what does it means when I set my disk to LRU . Does it mean that both cache dirs will be actively used ? 4. How to limit concurrent users? 5. Can we limit the usage of memory for SQUID? I would appreciate is someone can shed some light on the cache issue and how to manage multiple caches with expiry times etc... also any tips are appreciated. Thank you so much. Really appreacite answers from any of you guys.. -Zabrina - Regards, Zabrina Mohamad Infrastructure Management & Operations Information Technology Department Disclaimer Note.
