Hello, I use Boost.ASIO for receiving Twitter JSON data. I use this code: boost::asio::write( p_socket, l_request ); boost::asio::streambuf l_response; boost::asio::read_until(p_socket, l_response, "\r\n\r\n"); So in my optional the l_response variable should be read the full HTTP header. But if I write it to the std::cout I get: HTTP/1.1 200 OK Date: Fri, 29 Jul 2011 20:08:37 GMT Server: hi Cache-Control: max-age=15, must-revalidate, max-age=300 Expires: Fri, 29 Jul 2011 20:13:37 GMT Content-Type: application/json;charset=utf-8 Content-Length: 9763 Vary: Accept-Encoding X-Varnish: 1045274856 Age: 0 Via: 1.1 varnish X-Cache-Svr: smf1-aba-35-sr2.prod.twitter.com X-Cache: MISS Connection: close {"completed_in":0.025,"max_id":97033383951081472,"max_id_str":"97033383951081472","next_page":"?page=2&max_id=9703338395108147 I can change the "until read parameter" to \n, Connection: close or something else, but the read_until method does not stop the reading at the correct chars. Same code on a Wikipedia call runs without problems. Can anyone help me please to receive the correct header? Thanks Phil
