A freshly installed or restarted[1] proxy has a cache in state called "cold". Each repeat fetch for a URL "warms" it.URL which are often requested are called "hot". You have to make one request where a MISS is guaranteed. That request tells Squid whether to cache the reply for *future* use. All that first request will tell you is whether the URL is possible to fetch. Nothing about caching in access.log. To know if a reply has been cached requires at least a second request. That ones access.log details say whether *it* was a hit or miss or refresh. [1] disk cache persist across restart. So simply restarting Squid resets to either cold or warm states depending on disk usage. Usually the hottest objects will be exclusively in RAM and the latest copy need fetching from the network on restart - this ensures that hot objects are always up to date and accurate. > 2.

At least not now. So far it has been your testing methodology which is broken, not the sites operation. (Except that one doing Vary:User-Agent and nothing can be done in squid.conf about that.) Many of the refresh_pattern override/ignore options *break* HTTP and are only to be used if you understand the impact of what that use means, with a specific broken website that requires it. You need to know exactly *what* is broken about the website to be able to configure the overrides correctly for it. If you want better caching, ensure that you have the latest Squid available. We are constantly searching out ways to safely improve the amount Squid can store and remove the need for those overrides to exist at all. > 3.

The servers clock is out of sync. And there is again only one fetch for each object in your log so no way to know if they are cold requests or whats going on. bit of a mstery even why mapa3.png *does* HIT.
