Depends on how cache aware the web site was. If the web site did this
correctly in a planned manner they set the expiry date on the old content
to shortly before they planned on doing the update.
Most don't and in such case Squid guesses how often the content is updated
based on how old it is. See refresh_pattern.

Yes.
