```
@FunctionalInterface
public interface IResponseFilter
```
A response filter can be added to the RequestCycleSettings.addResponseFilter(IResponseFilter) object. This will be called from the Buffered Response objects right before they would send it to the real responses. You have to use the RequestCycleSettings.setBufferResponse(boolean)(to true which is the default) for this filtering to work.
