Hi - We run Win2k3 with Isa 2004 (2 nic's). I notice that when we change pages in our website, the changes are not seen from outside. I turned off http caching in the (default) rule, and then in works fine. I read somewhere that a new rule should be created to allow only caching from the internal network and not from outside. My questions: 1. why are pages not refreshed with http caching on? 2. how should a rule look like to accomplish the above
