/**
 * @file
 * Drupal site-specific configuration file.
 *
 * IMPORTANT NOTE:
 * This file may have been set to read-only by the Drupal installation program.
 * If you make changes to this file, be sure to protect it again after making
 * your modifications. Failure to remove write permissions to this file is a
 * security risk.
 *
 * In order to use the selection rules below the multisite aliasing file named
 * sites/sites.php must be present. Its optional settings will be loaded, and
 * the aliases in the array $sites will override the default directory rules
 * below. See sites/example.sites.php for more information about aliases.
 *
 * The configuration directory will be discovered by stripping the website's
 * hostname from left to right and pathname from right to left. The first
 * configuration file found will be used and any others will be ignored. If no
 * other configuration file is found then the default configuration file at
 * 'sites/default' will be used.
 *
 * For example, for a fictitious site installed at
 * http://www.drupal.org:8080/mysite/test/, the 'settings.php' file is searched
 * for in the following directories:
 *
 * - sites/8080.www.drupal.org.mysite.test
 * - sites/www.drupal.org.mysite.test
 * - sites/drupal.org.mysite.test
 * - sites/org.mysite.test
 *
 * - sites/8080.www.drupal.org.mysite
 * - sites/www.drupal.org.mysite
 * - sites/drupal.org.mysite
 * - sites/org.mysite
 *
 * - sites/8080.www.drupal.org
 * - sites/www.drupal.org
 * - sites/drupal.org
 * - sites/org
 *
 * - sites/default
 *
 * Note that if you are installing on a non-standard port number, prefix the
 * hostname with that number. For example,
 * http://www.drupal.org:8080/mysite/test/ could be loaded from
 * sites/8080.www.drupal.org.mysite.test/.
 *
 * @see example.sites.php
 * @see conf_path()
 *
 * In addition to customizing application settings through variables in
 * settings.php, you can create a services.yml file in the same directory to
 * register custom, site-specific service definitions and/or swap out default
 * implementations with custom ones.

/**
 * Database settings:
 *
 * The $databases array specifies the database connection or
 * connections that Drupal may use.  Drupal is able to connect
 * to multiple databases, including multiple types of databases,
 * during the same request.
 *
 * Each database connection is specified as an array of settings,
 * similar to the following:
 * @code
 * array(
 *   'driver' => 'mysql',
 *   'database' => 'databasename',
 *   'username' => 'username',
 *   'password' => 'password',
 *   'host' => 'localhost',
 *   'port' => 3306,
 *   'prefix' => 'myprefix_',
 *   'collation' => 'utf8_general_ci',
 * );
 * @endcode
 *
 * The "driver" property indicates what Drupal database driver the
 * connection should use.  This is usually the same as the name of the
 * database type, such as mysql or sqlite, but not always.  The other
 * properties will vary depending on the driver.  For SQLite, you must
 * specify a database file name in a directory that is writable by the
 * webserver.  For most other drivers, you must specify a
 * username, password, host, and database name.
 *
 * Transaction support is enabled by default for all drivers that support it,
 * including MySQL. To explicitly disable it, set the 'transactions' key to
 * FALSE.
 * Note that some configurations of MySQL, such as the MyISAM engine, don't
 * support it and will proceed silently even if enabled. If you experience
 * transaction related crashes with such configuration, set the 'transactions'
 * key to FALSE.
 *
 * For each database, you may optionally specify multiple "target" databases.
 * A target database allows Drupal to try to send certain queries to a
 * different database if it can but fall back to the default connection if not.
 * That is useful for primary/replica replication, as Drupal may try to connect
 * to a replica server when appropriate and if one is not available will simply
 * fall back to the single primary server (The terms primary/replica are
 * traditionally referred to as master/slave in database server documentation).
 *
 * The general format for the $databases array is as follows:
 * @code
 * $databases['default']['default'] = $info_array;
 * $databases['default']['replica'][] = $info_array;
 * $databases['default']['replica'][] = $info_array;
 * $databases['extra']['default'] = $info_array;
 * @endcode
 *
 * In the above example, $info_array is an array of settings described above.
 * The first line sets a "default" database that has one primary database
 * (the second level default).  The second and third lines create an array
 * of potential replica databases.  Drupal will select one at random for a given
 * request as needed.  The fourth line creates a new database with a name of
 * "extra".
 *
 * For a single database configuration, the following is sufficient:
 * @code
 * $databases['default']['default'] = array(
 *   'driver' => 'mysql',
 *   'database' => 'databasename',
 *   'username' => 'username',
 *   'password' => 'password',
 *   'host' => 'localhost',
 *   'prefix' => 'main_',
 *   'collation' => 'utf8_general_ci',
 * );
 * @endcode
 *
 * You can optionally set prefixes for some or all database table names
 * by using the 'prefix' setting. If a prefix is specified, the table
 * name will be prepended with its value. Be sure to use valid database
 * characters only, usually alphanumeric and underscore. If no prefixes
 * are desired, leave it as an empty string ''.
 *
 * To have all database names prefixed, set 'prefix' as a string:
 * @code
 *   'prefix' => 'main_',
 * @endcode
 * To provide prefixes for specific tables, set 'prefix' as an array.
 * The array's keys are the table names and the values are the prefixes.
 * The 'default' element is mandatory and holds the prefix for any tables
 * not specified elsewhere in the array. Example:
 * @code
 *   'prefix' => array(
 *     'default'   => 'main_',
 *     'users'     => 'shared_',
 *     'sessions'  => 'shared_',
 *     'role'      => 'shared_',
 *     'authmap'   => 'shared_',
 *   ),
 * @endcode
 * You can also use a reference to a schema/database as a prefix. This may be
 * useful if your Drupal installation exists in a schema that is not the default
 * or you want to access several databases from the same code base at the same
 * time.
 * Example:
 * @code
 *   'prefix' => array(
 *     'default'   => 'main.',
 *     'users'     => 'shared.',
 *     'sessions'  => 'shared.',
 *     'role'      => 'shared.',
 *     'authmap'   => 'shared.',
 *   );
 * @endcode
 * NOTE: MySQL and SQLite's definition of a schema is a database.
 *
 * Advanced users can add or override initial commands to execute when
 * connecting to the database server, as well as PDO connection settings. For
 * example, to enable MySQL SELECT queries to exceed the max_join_size system
 * variable, and to reduce the database connection timeout to 5 seconds:
 *
 * @code
 * $databases['default']['default'] = array(
 *   'init_commands' => array(
 *     'big_selects' => 'SET SQL_BIG_SELECTS=1',
 *   ),
 *   'pdo' => array(
 *     PDO::ATTR_TIMEOUT => 5,
 *   ),
 * );
 * @endcode
 *
 * WARNING: These defaults are designed for database portability. Changing them
 * may cause unexpected behavior, including potential data loss.
 *
 * @see DatabaseConnection_mysql::__construct
 * @see DatabaseConnection_pgsql::__construct
 * @see DatabaseConnection_sqlite::__construct

 * Database configuration format:
 * @code
 *   $databases['default']['default'] = array(
 *     'driver' => 'mysql',
 *     'database' => 'databasename',
 *     'username' => 'username',

 *
 * The default location for the active and staging directories is inside a

 * can enhance security by putting the active configuration outside your

/**
 * Reverse Proxy Configuration:
 *
 * Reverse proxy servers are often used to enhance the performance
 * of heavily visited sites and may also provide other site caching,
 * security, or encryption benefits. In an environment where Drupal
 * is behind a reverse proxy, the real IP address of the client should
 * be determined such that the correct client IP address is available
 * to Drupal's logging, statistics, and access management systems. In
 * the most simple scenario, the proxy server will add an
 * X-Forwarded-For header to the request that contains the client IP
 * address. However, HTTP headers are vulnerable to spoofing, where a
 * malicious client could bypass restrictions by setting the
 * X-Forwarded-For header directly. Therefore, Drupal's proxy
 * configuration requires the IP addresses of all remote proxies to be
 * specified in $settings['reverse_proxy_addresses'] to work correctly.
 *
 * Enable this setting to get Drupal to determine the client IP from
 * the X-Forwarded-For header (or $settings['reverse_proxy_header'] if set).
 * If you are unsure about this setting, do not have a reverse proxy,
 * or Drupal operates in a shared hosting environment, this setting
 * should remain commented out.
 *
 * In order for this setting to be used you must specify every possible
 * reverse proxy IP address in $settings['reverse_proxy_addresses'].
 * If a complete list of reverse proxies is not available in your
 * environment (for example, if you use a CDN) you may set the
 * $_SERVER['REMOTE_ADDR'] variable directly in settings.php.
 * Be aware, however, that it is likely that this would allow IP
 * address spoofing unless more advanced precautions are taken.

 * header as the user who originally requested the cached page. Without "Vary:
 * Cookie", authenticated users would also be served the anonymous page from
 * the cache. If the site has mostly anonymous users except a few known
 * editors/administrators, the Vary header can be omitted. This allows for
 * better caching in HTTP proxies (including reverse proxies), i.e. even if
 * clients send different cookies, they still get content served from the cache.
