For one of our branch campuses, I've setup scheduled download of our
corporate web site daily once every morning. When changes are made to
the
corporate web site during the day, they do not reflect for the branch
campus
users. If I change the schedule to download several times daily, does
that
not defeat the purpose of caching?

Is there a better way to minimize traffic and still be able for users
to see
the latest changes?

When you schedule downloads, does proxy re-cache everything, or only
changed
files?

Thanks, I'm not too familiar with proxying.
