minumum_expiry_time directive

        The minimum caching time according to (Expires - Date)
        Headers Squid honors if the object can't be revalidated
        defaults to 60 seconds. In reverse proxy enorinments it
        might be desirable to honor shorter object lifetimes. It
        is most likely better to make your server return a
        meaningful Last-Modified header however.
