Subject Re: streaming responses

There's no special magic involved. Make sure you use
HttpMethod#getResponseBodyAsStream, which will return the raw input
stream, and not its buffering counterparts
HttpMethod#getResponseBodyAsString and HttpMethod#getResponseBody.

You should not worry about chunking. HttpClient will decode chunked
input on fly, if necessary. Just grab the raw input stream and do
whatever response retrieval suits your application best.

Hope this helps
