Class FilterContext<T>

java.lang.Object

org.asynchttpclient.filter.FilterContext<T>

Type Parameters:

T - the handler result type

public class FilterContext<T>
extends Object

A FilterContext can be used to decorate Request and AsyncHandler from a list of RequestFilter. RequestFilter gets executed before the HTTP request is made to the remote server. Once the response bytes are received, a FilterContext is then passed to the list of ResponseFilter. ResponseFilter gets invoked before the response gets processed, e.g. before authorization, redirection and invocation of AsyncHandler gets processed.
Invoking getResponseStatus() returns an instance of HttpResponseStatus that can be used to decide if the response processing should continue or not. You can stop the current response processing and replay the request but creating a FilterContext. The AsyncHttpClient will interrupt the processing and "replay" the associated Request instance.
