 * - `Session.defaults` - The default configuration set to use as a basis for your session.

 * - `Session.handler` - Can be used to enable a custom session handler.  Expects an array of of callables,

 * - `Session.autoRegenerate` - Enabling this setting, turns on automatic renewal of sessions, and

 * - `Session.ini` - An associative array of additional ini values to set.
 *
 * The built in defaults are:
 *
 * - 'php' - Uses settings defined in your php.ini.
 * - 'cake' - Saves session files in CakePHP's /tmp directory.
 * - 'database' - Uses CakePHP's database sessions.
 * - 'cache' - Use the Cache class to save sessions.
 *
 * To define a custom session handler, save it at /app/Model/Datasource/Session/<name>.php.
