 * It automatically adds a **cache name** prefix to the cache keys based on the object type stored in the cache. Default cache name is the full name of the cache item class (`CacheItem` postfix is removed if your cache item class ends with it). You can use the **`CacheName` attribute** on the cache item class to set the cache name.
 * It automatically adds the **current tenant id** to the cache key to distinguish cache items for different tenants (if your application is [multi-tenant](Multi-Tenancy.md)). Define `IgnoreMultiTenancy` attribute on the cache item class to disable this if you want to share the cached objects among all tenants in a multi-tenant application.
 * Allows to define a **global cache key prefix** per application, so different applications can use their isolated key pools in a shared distributed cache server.
