/****************************************************************** * * CyberHTTP for Java * * Copyright (C) Satoshi Konno 2002-2004 * * File: HTTPConnection.java * * Revision; * * 11/18/02 * - first revision. * 09/02/03 * - Giordano Sassaroli <sassarol@cefriel.it> * - Problem : The API is unable to receive responses from the Microsoft UPnP stack * - Error : the Microsoft UPnP stack is based on ISAPI on IIS, and whenever IIS * receives a post request, it answers with two responses: the first one has no * body and it is a code 100 (continue) response, which has to be ignored. The * second response is the actual one and should be parsed as the response. * 02/09/04 * - Ralf G. R. Bergs" <Ralf@Ber.gs> * - Why do you strip leading and trailing white space from the response body? * - Disabled to trim the content string. * 03/11/04 * - Added some methods about InputStream content. * setContentInputStream(), getContentInputStream() and hasContentInputStream(). * 03/16/04 * - Thanks for Darrell Young * - Added setVersion() and getVersion(); * 03/17/04 * - Added hasFirstLine(); * 05/26/04 * - Jan Newmarch <jan.newmarch@infotech.monash.edu.au> (05/26/04) * - Changed setCacheControl() and getChcheControl(); * 08/25/04 * - Added the following methods. * hasContentRange(), setContentRange(), getContentRange(), * getContentRangeFirstPosition(), getContentRangeLastPosition() and getContentRangeInstanceLength() * 08/26/04 * - Added the following methods. * hasConnection(), setConnection(), getConnection(), * isCloseConnection() and isKeepAliveConnection() * 08/27/04 * - Added a updateWithContentLength paramger to setContent(). * - Changed to HTTPPacket::set() not to change the header of Content-Length. * 08/28/04 * - Added init() and read(). * 09/19/04 * - Added a onlyHeaders parameter to set(). * 10/20/04 * - Brent Hills <bhills@openshores.com> * - Changed hasContentRange() to check Content-Range and Range header. * - Added support for Range header to getContentRange(). * 02/02/05 * - Mark Retallack <mretallack@users.sourceforge.net> * - Fixed set() not to read over the content length when the stream is keep alive. * 02/28/05 * - Added the following methods for chunked stream support. * hasTransferEncoding(), setTransferEncoding(), getTransferEncoding(), isChunked(). * 03/02/05 * - Changed post() to suppot chunked stream. * 06/11/05 * - Added setHost(). * 07/07/05 * - Lee Peik Feng <pflee@users.sourceforge.net> * - Andrey Ovchar <AOvchar@consultitnow.com> * - Fixed set() to parse the chunk size as a hex string. * 11/02/05 * - Changed set() to use BufferedInputStream instead of BufferedReader to * get the content as a byte stream. * 11/06/05 * - Added getCharSet(). * - Changed getContentString() to return the content string using the charset. * *******************************************************************/ package org.cybergarage.http;
