Now that your expectations have been lowered ... *correct* usage is not to have any of the override-* or ignore-* options at all. But correct and practical are not always the same. Use the options if you are required to, but only then. There is also a very large diference betwen HTTP/1.0 caching and HTTP/1.1 caching you need to be aware of. In HTTP/1.0 there was HIT/MISS and very little else. In HTTP/1.1 there is also revalidation (304, REFRESH, IMS, INM) which is caching the [large] bodies of objects while still sending the [small] headers back and forth - giving the best of both worlds. So tile1893... what version of Squid do you have? how are you testing it? what makes you think its not caching? how much cache space do you have? what are your maximum object limits? what order is your cache, store and object related config options? what traffic rate (requests per second/minute) are you serving? what does redbot.org say about the URLs you are trying to cache? (Maybe more later but that should do for starters.) Amos
