isExpired method

bool isExpired(CacheControl rqCacheCtrl)

Checks if response is expired.

Implementation

bool isExpired(CacheControl rqCacheCtrl) {
  final ageMillis = _cacheResponseAge();
  var freshMillis = _computeFreshnessLifetime();

  final maxAge = rqCacheCtrl.maxAge;
  if (maxAge > -1) {
    freshMillis = min(freshMillis, maxAge * 1000);
  }

  final maxStaleMillis =
      (!cacheControl.mustRevalidate && rqCacheCtrl.maxStale > -1)
          ? rqCacheCtrl.maxStale * 1000
          : 0;
  final minFreshMillis = max(0, rqCacheCtrl.minFresh * 1000);

  if (!cacheControl.noCache &&
      ageMillis + minFreshMillis < freshMillis + maxStaleMillis) {
    return false;
  }

  return true;
}
