  if (upgrade != nullptr) {
    const Router::RouteEntry::UpgradeMap* upgrade_map = filter_manager_callbacks_.upgradeMap();

    if (filter_chain_factory_.createUpgradeFilterChain(upgrade->value().getStringView(),
                                                       upgrade_map, *this)) {
      filter_manager_callbacks_.upgradeFilterChainCreated();
      return true;
    } else {
      upgrade_rejected = true;
      // Fall through to the default filter chain. The function calling this
      // will send a local reply indicating that the upgrade failed.
    }
  }
  //  create here !
  filter_chain_factory_.createFilterChain(*this);
  return !upgrade_rejected;
}
