MiddlewareHandler (handler 2.0.11 API)

All Superinterfaces:

io.undertow.server.HttpHandler, LightHttpHandler
```
public interface MiddlewareHandler
extends LightHttpHandler
```
A interface for middleware handlers. All middleware handlers must implement this interface so that the handler can be plugged in to the request/response chain during server startup with SPI (Service Provider Interface). The entire light-4j framework is a core server that provides a plugin structure to hookup all sorts of plugins to handler different cross-cutting concerns. The middleware handlers are designed based on chain of responsibility pattern. This handler extends LightHttpHandler which has a default method to handle the error status response.
