We now have a small upgrade release ready which incorporates a set of new features that were discussed on the <www-lib@w3.org> mailing list. Most noticeable in this release is the support for posting data objects from memory and the server model implemented by the mini server is now in place. The full list of new features is listed below or you can get it from http://www.w3.org/pub/WWW/Library/User/ReleaseNotes.html Also, please remember that the Library does not do automatic redirection anymore as many applications do not want this. Instead you can register a HTNet callback function to handle redirection. You can find examples in both the Command line tool and the Line Mode browser. Also, Eric and I have now solved the problems of getting the Line Mode Browser to compile on Windows 95. The problem was that the asynchronous window handles has to be treated differently from earlier versions. The distribution files are available from http://www.w3.org/pub/WWW/Distribution.html Comments are welcome!

This module is a part of the WWWUtils interface and it handles better management of dynamic memory. You can find a full description at http://www.w3.org/pub/WWW/Library/User/Using/Memory.html * We have an updated list of all public functions exported from the Library. It's available as wwwlist.txt * We also present an updated list of all public interfaces available in the Library. You can find it in the Library Internals. * PUT and POST from memory is implemented. You can now post data from memory using the POSTWeb model as for posting remote data objects. The Interface is described in HTAccess module. There is a very small dummy test implemented in the Line Mode browser. You can activate it if you type edit from the command line. * The Mini server now runs (although crude) as a proxy. It is capable of serving data as a HTTP/HTTP proxy. It is based on the internal Library event loop and is therefore highly portable. It is not intended to be a full featured server but a test implementation which shows how to use the Library in server applications. * Bug fixed that caused the following problem: If there hasn't been made a connection between the net->target and the request->output_stream then the latter is not freed if the request is interrupted. * The referer URL header can now contain a unlimited length URL * A resolver callback function has been introduced in the HTTee stream. This allows the caller to assign a callback function to resolve conflicts between the return codes of the two streams. * The request object as been added as a calling parameter to the HTFWrite stream creation method. This allows errors from writing to a file to propagate back to the request object. * The three streams HTSaveLocally, HTSaveAndExecute and HTSaveAndCallBack * have been optimized and they now all use the HTFWrite stream creation method * We have a new module called HTTPGen. It generates general HTTP headers. These headers were a part of the MIME header generator, but by isolating them, we can use the MIME header as a generic MIME entity header generator. * Created HTErrorStream which always returns HT_ERROR. It replaces the HTBlackHole has been replace with HTErrorStream in many places in order to speed up performance * Made HTTP response stream (which parses the response line only) into a converter so that we can forward the output exactly as received from the remote HTTP server. This is important for proxy applications and other applications that want to see the output untouched. * The HTChunk module has been made more solid and the amount of memory allocations has been limited. * Memory cleanup fixed in content length counter stream and FTP module * Introducing HT_CLOSED and HT_PAUSE for handling streams. This was required especially after HTTP supports persistent connections where a document is not delimited by a closed connection. -- Henrik Frystyk Nielsen, <frystyk@w3.org> World-Wide Web Consortium, MIT/LCS NE43-356 545 Technology Square, Cambridge MA 02139, USA
