 **`ICacheService` is coming from the Coffeespace.Core class library. There are generic services and settings, which can be used across microservices.**
 
-Caching is implemented in `Ordering API` and `Product API` using `*Proxy*` pattern. `Ordering API` uses [Mediator's](https://github.com/martinothamar/Mediator) notifications to move cache invalidation logic into `Notification Handler`.
-```cs
-internal sealed class OrderCacheNotificationHandler : 
-    INotificationHandler<CreateOrderNotification>,
-    INotificationHandler<UpdateOrderNotification>,
-    INotificationHandler<DeleteOrderNotification>
