public abstract class AbstractResponseHandler<T>
extends java.lang.Object
implements ResponseHandler<T>

A generic ResponseHandler that works with the response entity for successful (2xx) responses. If the response code was >= 300, the response body is consumed and an HttpResponseException is thrown.

If this is used with HttpClient.execute( org.apache.http.client.methods.HttpUriRequest, ResponseHandler), HttpClient may handle redirects (3xx responses) internally.
