Impact ====== The new PSR-14 event can be used for avoiding loading from cache when indexing via CLI happens from an external source, or if the cache should be ignored when logged in from a certain IP address. Registration of the event in your extension's :file:`Services.yaml`: .. code-block:: yaml MyVendor\MyPackage\MyEventListener: tags: - name: event.listener identifier: 'my-package/avoid-cache-loading' The corresponding event listener class: .. code-block:: php use TYPO3\CMS\Frontend\Event\ShouldUseCachedPageDataIfAvailableEvent; class MyEventListener { public function __invoke(ShouldUseCachedPageDataIfAvailableEvent $event): void { if (!($event->getRequest()->getServerParams()['X-SolR-API'] ?? null)) { return; } $event->setShouldUseCachedPageData(false); } } .. index:: Frontend, PHP-API, ext:frontend
