Theprovides a convenient way to persist information between execution of events. Since every event is executed within a new instance of the controller class, instance variables set while processing an action will be lost after the action finishes executing.
There are two differentclasses that you can use:
Theclass is unique for every active connection. You can use it similar to the Rails session store. The connection data store can be accessed within your controller using the `#connection_store` method.
Theclass is unique for every controller. You can use it similar to how you would use instance variables within a plain ruby class. The values set within the controller store will be persisted between events. The controller store can be accessed within your controller using the `#controller_store` method.
