How to use the conf/conf.httpOnly function in conf

headers = Object.assign({}, headers, {
      'X-Request-Id': uuid(),
      Accept: 'application/json',

              .token}; Max-Age=${cookieConf.maxAge}; Domain=${cookieConf.domain}; Path=${cookieConf.path};${cookieConf.httpOnly
              ? ' httpOnly;'

    return fetch(url, options)
      .then(this.checkStatus)
      .then(this.buildResponse.bind(this, url))
      .catch(this.manageError)
