If we set the `expiresAfter` option in metarefresh's config, we effectively alter the inbound metadata. Thus when we're conditionally GETting, we need to be aware that we've introduced a validUntil attribute that the remote server may not know about. That means we might need to force a refresh of the source even if the remote server does not think it has been modified.

Because metarefresh is typically called periodically by cron, we can't force the refresh at exactly the expiry time. To avoid metadata expiring between calls, we need a bit of a buffer. The choice of one hour for the buffer is essentially arbitrary, but based on the example config setting 'cron' => ['hourly'].
