parameters:
  session.storage.options:
    # Default ini options for sessions.
    #
    # Some distributions of Linux (most notably Debian) ship their PHP
    # installations with garbage collection (gc) disabled. Since Drupal depends
    # on PHP's garbage collection for clearing sessions, ensure that garbage
    # collection occurs by using the most common settings.
    # @default 1
    gc_probability: 1
    # @default 100
    gc_divisor: 100
    #
    # Set session lifetime (in seconds), i.e. the grace period for session
    # data. Sessions are deleted by the session garbage collector after one
    # session lifetime has elapsed since the user's last visit. When a session
    # is deleted, authenticated users are logged out, and the contents of the
    # user's session is discarded.
    # @default 200000
    gc_maxlifetime: 200000
    #
    # Set session cookie lifetime (in seconds), i.e. the time from the session
    # is created to the cookie expires, i.e. when the browser is expected to
    # discard the cookie. The value 0 means "until the browser is closed".
    # @default 2000000
    cookie_lifetime: 2000000
    #
    # Drupal automatically generates a unique session cookie name based on the
    # full domain name used to access the site. This mechanism is sufficient
    # for most use-cases, including multi-site deployments. However, if it is
    # desired that a session can be reused across different subdomains, the
    # cookie domain needs to be set to the shared base domain. Doing so assures
    # that users remain logged in as they cross between various subdomains.
    # To maximize compatibility and normalize the behavior across user agents,
    # the cookie domain should start with a dot.
    #
    # @default none
    # cookie_domain: '.example.com'
    #
    # Set the session ID string length. The length can be between 22 to 256. The
    # PHP recommended value is 48. See
    # https://www.php.net/manual/session.security.ini.php for more information.
    # This value should be kept in sync with
    # \Drupal\Core\Session\SessionConfiguration::__construct()
    # @default 48
    sid_length: 48
    #
    # Set the number of bits in encoded session ID character. The possible
    # values are '4' (0-9, a-f), '5' (0-9, a-v), and '6' (0-9, a-z, A-Z, "-",
    # ","). The PHP recommended value is 6. See
    # https://www.php.net/manual/session.security.ini.php for more information.
    # This value should be kept in sync with

    # Twig debugging:
    #
    # When debugging is enabled:
    # - The markup of each Twig template is surrounded by HTML comments that
    #   contain theming information, such as template file name suggestions.
    # - Note that this debugging markup will cause automated tests that directly
    #   check rendered HTML to fail. When running automated tests, 'debug'
    #   should be set to FALSE.
    # - The dump() function can be used in Twig templates to output information
    #   about template variables.
    # - Twig templates are automatically recompiled whenever the source code
    #   changes (see auto_reload below).
    #
    # For more information about debugging Twig templates, see
    # https://www.drupal.org/node/1906392.
    #
    # Enabling Twig debugging is not recommended in production environments.

    # Twig auto-reload:
    #
    # Automatically recompile Twig templates whenever the source code changes.
    # If you don't provide a value for auto_reload, it will be determined
    # based on the value of debug.
    #
    # Enabling auto-reload is not recommended in production environments.
    # @default null
    auto_reload: null
    # Twig cache:
    #
    # By default, Twig templates will be compiled and stored in the filesystem
    # to increase performance. Disabling the Twig cache will recompile the
    # templates from source each time they are used. In most cases the
    # auto_reload setting above should be enabled rather than disabling the
    # Twig cache.
    #
    # Disabling the Twig cache is not recommended in production environments.
    # @default true

    # File extensions:
    #
    # List of file extensions the Twig system is allowed to load via the
    # twig.loader.filesystem service. Files with other extensions will not be
    # loaded unless they are added here. For example, to allow a file named
    # 'example.partial' to be loaded, add 'partial' to this list. To load files
    # with no extension, add an empty string '' to the list.

    required_cache_contexts: ['languages:language_interface', 'theme', 'user.permissions']
    # Renderer automatic placeholdering conditions:
    #
    # Drupal allows portions of the page to be automatically deferred when
    # rendering to improve cache performance. That is especially helpful for
    # cache contexts that vary widely, such as the active user. On some sites
    # those may be different, however, such as sites with only a handful of
    # users. If you know what the high-cardinality cache contexts are for your
    # site, specify those here. If you're not sure, the defaults are fairly safe
    # in general.
