* Redis Session implements a session component using [redis](https://redis.io/) as the storage medium.
*
* Redis Session requires redis version 2.6.12 or higher to work properly.
*
* It needs to be configured with a redis [[Connection]] that is also configured as an application component.
* By default it will use the `redis` application component.
*
* To use redis Session as the session application component, configure the application as follows,
*
* ~~~
* [
* 'components' => [
* 'session' => [
* 'class' => 'yii\redis\Session',
* 'redis' => [
* 'hostname' => 'localhost',
* 'port' => 6379,
* 'database' => 0,
* ]
* ],
* ],
* ]
* ~~~
*
* Or if you have configured the redis [[Connection]] as an application component, the following is sufficient:
*
* ~~~
* [
* 'components' => [
* 'session' => [
* 'class' => 'yii\redis\Session',
* // 'redis' => 'redis' // id of the connection application component
* ],
* ],
* ]
* ~~~
*
* @property-read bool $useCustomStorage Whether to use custom storage.
