expires property

DateTime expires

The date and time after which the response's data should be considered stale.

This is parsed from the Expires header in headers. If headers doesn't have an Expires header, this will be null.

Implementation

DateTime get expires {
  if (_expiresCache != null) return _expiresCache;
  if (!headers.containsKey('expires')) return null;
  _expiresCache = parseHttpDate(headers['expires']);
  return _expiresCache;
}
