You emptied the cache, or at least altered the cache_dir line to point at a new empty cache_dir during the test after disabling the helper? anything it might have done to the cache contents is already done to the data stored there by the time you disable it. > I've been reading some older mails from the list and a guy named Hussam > Al-Tayeb exchanged some interesting mails with you a couple of months > ago ..

It is a critical internal validity check for the cache index itself. Preventing the contents of say your bank account display page being sent to someone else fetching http://google.com/. That kind of critical. If the Vary meta object is not pointing at the object its supposed to be. Then the object it was supposed to be pointing at could be anything at all. For your other question. Yes, 3.5 has the store_miss directive now. <http://master.squid-cache.org/Doc/config/store_miss/>. You can use ACLs in there to check for either the known URLs or the Vary header existence on replies and prevent caching of those objects. I'm not sure how that will interact with the vary objects in your case but none I know of using it has mentioned any issues.
