Re: [squid-users] Squid no_cache and msn's gaming zone

You may need to clean out your cache as well. The no_cache directive
only stops new files from being cached. There will still be hits for
already cached files.

It may be possible to disregard the cached files by constructing a very
aggressive refresh_pattern that makes the objects stale.
