 *
 * * {@link withNoHttpTransferCache} to disable HTTP transfer cache
 * * {@link withHttpTransferCacheOptions} to configure some HTTP transfer cache options
 * * {@link withI18nSupport} to enable hydration support for i18n blocks
 * * {@link withEventReplay} to enable support for replaying user events
