Callback interface to submit HTTP responses asynchronously.
 The NHttpRequestHandler.handle(HttpRequest, HttpResponse, NHttpResponseTrigger, HttpContext) method does not have to submit a response immediately. It can defer transmission of the HTTP response back to the client without blocking the I/O thread by delegating the process of handling the HTTP request to a worker thread. The worker thread in its turn can use the instance of NHttpResponseTrigger passed as a parameter to submit a response as at a later point of time once the response becomes available. 
Since:
4.0
Deprecated:
(4.2) use HttpAsyncExchange/**
