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,
, batch tools
, etc. Pluggable modules provided with libwww
include complete HTTP/1.1
(with caching, pipelining, PUT, POST,
Digest Authentication, deflate, etc), MySQL
(SiRPAC), WebDAV, and much more.
The purpose of libwww is to serve as a testbed for protocol experiments.

- October 21 2005: Packaging of the libwww 5.4.1 release. This maintenance release
fixes some SSL issues, brings the configure scripts up to date and fixes
a security vulnerability in HTBound.c
- 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 the
config/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
- December 20 2000: Release of libwww 5.3.2. This release includes enhancements
in the RDF parser and many bug fixes, principally in the cache, the
chunk, and the hash modules. Check the release notes for more information.
- 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.

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

- 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.
- Jul 7 1999: libwww-SSL library is available
for testing in the US! Thanks to Jeff Schiller who have made his
export controlled server available, we can distribute Olga's glue code
between openSSL and libwww. It should run on both Unix and Windows - try
