@umennel Careful -- this actually breaks previous behavior. Now, unless you set remove_chunk_markers to true, the following code will produce a chunked-encoded string:

http::client client;
http::client::request request("http://www.boost.org:80/");
http::client::response response = client.get(request);
std::cerr << body(response) << std::endl;

@deanberris Is this what we want?

To put it another way, can you think of a case where we wouldn't want remove_chunk_markers to default to true?

@igorpeshansky, indeed, the default should be true. Otherwise it is hard to keep the behavior consistent. We should decide on this before merging into 0.13.
