Libwww - the W3C Protocol Library

Libwww is a highly modular, general-purpose client side Web API written in C for Unix and Windows (Win32). It's well suited for both small and large applications,like browser/editors, robots, batch tools, etc. Pluggable modules provided with libwww include complete HTTP/1.1 (with caching, pipelining, PUT, POST, Digest Authentication, deflate, etc), MySQL logging, FTP, HTML/4, XML(expat), RDF (SiRPAC), WebDAV, and much more. The purpose of libwww is to serve as a testbed for protocol experiments.

January 29, 2004: Results of the future of Libwww survey. W3C is handling over development of libwww to the Open Source community. Check the announcement for more info.
September 2, 2003: Future of Libwww Survey. W3C has stopped work on libwww and invites the libwww user community to participate in a Future of Libwww Survey that will help to determine its future. A public W3C account is required to complete the survey. This survey will close on September 30. Read about W3C Open Source Software.

June 12 2002: Re-packaging of the libwww 5.4.0 release. The packages were missing the Win32 makefile files. If you had already downloaded the previous package and are missing these files, the missing files are also available in the libwww-win32.zip package. The Installation guide gives more information on how to get you set up.
June 10 2002: Release of the libwww 5.4.0 WIN32 precompiled binary package. This is a companion package to the latest libwww distribution and includes precompiled versions of the libwww DLL files, as well as most of the libwww applications, including the Web Commander..
June 7 2002: Release of libwww 5.4.0. This release includes WebDAV support, enhancements in the RDF parser and some bug fixes. Check the release notes for more information.
**May 30 2002:**Update of the libwww WIN32 makefiles to include the DAV package. The zip package now also includes the .def files, as theconfig/winConfigure.pl script seems to have problems to generate them on some platforms.
May 30 2002: Manuele Kirschpi added WebDAV support to libwww. (well, this actually happened a couple of months ago, but I had forgotten to update this page).U

September 22 2000: libwwww survey. We're conducting a survey to try to find out who uses libwww and where should we take libwww next.
The survey has concluded, but I haven't had time to compile the results. Help is welcome.
Release of libwww 5.3.1. This release includes patches that mostly fix problems with the SSL interface and the Windows asynchronous event handler. The release notes give a more detailed change list. N.B., we decided to skip the 5.3.0 release number, as some people were already refering to the pre-release as the final release.
August 4 2000: Release of libwww 5.3.1. This release includes patches that mostly fix problems with the SSL interface and the Windows asynchronous event handler. The release notes give a more detailed change list. N.B., we decided to skip the 5.3.0 release number, as some people were already refering to the pre-release as the final release.
June 9 2000: Pre-release of libwww 5.3.0. It's been over a year since the last release. Libwww has continued to evolve and patches have been contributed. This release is a snapshot of the current state of the CVS base. In addition, thanks to a change in the US legislation, it now contains the source code for the SSL interface. As this is the first release since Henrik left, we have a testing period, to see if everything works OK, and to have time to finish upgrading the release notes. The change in the version reflects this as the first libwww user's community release of their own library (even if that sounds corny!) This code is available as usual from CVS.
Aug 29 1999: Using libwww with gtk James Henstridge: wrote up some event register/unregister functions that use the glib event loop. This makes libwww fit nicely into just about any gnome or gtk+ program. This code may be useful for other people wanting to use libwww with gtk.
