HttpResponseHandler
For example, if the object returned by this response handler manually
manages the stream of data from the HTTP connection, and doesn't read all
the data from the connection in the HttpResponseHandler.handle(HttpResponse)
method,
this method can be used to prevent the underlying connection from being
prematurely closed.
Response handlers should use this option very carefully, since it means that resource cleanup is no longer handled automatically, and if neglected, can result in the client runtime running out of resources for new HTTP connections.
