# 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.

  http.response.debug_cacheability_headers: true
