In other words, if you block the yahoo.com domain via an acl, reload squid and try to hit yahoo.com, if the page is in cache, Squid will serve it. Once you try to surf to a non-cached yahoo.com page, Squid will prevent that request from being served. Similarly, during the MAINT time listed above (12:32-12:35) no NEW pages will be cached, but any pages currently in cache will be served. This is all anecdotal experience and should not be relied on as truth. Chris
