ResponseCallback (Cmobilecom AF 5.19 Javadoc)

```
public interface ResponseCallback
```
For a synchronized request event, it will be handled with response during the same HTTP request. For an asynchronzed request event, its response will be set to a non-null dummy value by a module (indicating that the module will handle the event) during the same HTTP request, and its responseCallback will be called after the request event handling is completed in a subsequent HTTP request.
