RE: [squid-users] Re: Windows Update

How often does your cache update?
At the risk of sounding simplistic, perhaps you wouldn't want to cache this
in for the numerous and frequent updates that M$ posts to it's site. From my
perspective, I would avoid caching this site due to it's content.
Another thought is that this is a "no-cache" header for M$'s various
versions of Internet Explorer for the very same reasons. If someone's
browser is set to not update then this could possibly override that for the
very same reason.

Here are some samples from my more detailed log, could someone let me know
what's happening? Windows update just won't come off the cache. It looks to
me as if there is a "no-cache" header in the windows update site, so is
there
a way I can force it to cache? I can post the entire log file if you like
and
also the config. Thanks,

David
