# Local development services. # # The development.services.yml file allows the developer to override # container parameters for debugging. # # To activate this feature, follow the instructions at the top of the # 'example.settings.local.php' file, which sits next to this file. # # Be aware that in Drupal's configuration system, all the files that # provide container definitions are merged using a shallow merge approach # within \Drupal\Core\DependencyInjection\YamlFileLoader. # This means that if you want to override any value of a parameter, the # whole parameter array needs to be copied from # sites/default/default.services.yml or from core/core.services.yml file. parameters: http.response.debug_cacheability_headers: true services: cache.backend.null: class: Drupal\Core\Cache\NullBackendFactory
