I'm developing a mobile Web browser using libwww.
(a testbed for CC/PP)

FreeBSD, Linux and Solaris

Maybe between 'experience' and 'average'.

I have also used XML and HTML parsers before, but now
I switched them to my own parsers.

I made a tiny patch for FILE protocol (it was commited now),
which was the only modification I have made.

Sorry, but I couldn't get how do you mean by 'test'...

I don't think it is too big, but it often forces
application programmers to obey its policies,
and sometimes it is annoying.

For some typical applications, there are very useful and graceful
profiles, so that we can program such kinds of applications easily.

> [2.7] What are the things that you dislike the most of libwww

Incomplete memory frameworks, tightly coupled with unclearly layered
upcall systems.
Also the libwww's EventLst system seems not to have enough
scalability for productive applications.

Multi-thread support, and
flexible and functional event handlings.

No.
But I have borrowed several HTTP codes from wget
(<URL:http://sunsite.auc.dk/ftp/pub/infosystems/wget/>) before,
and it was very handy and easy to modify.
(though it does not support HTTP/1.1 pipeline functionalities)

I think I'm interested and will be able to help something to enhance
libwww, but I'm afraid I don't have enough time to spend for...

If we need a library written in C (and I think so),
libwww may have to be re-written in a more *C-like* style
than a current odd semi-OO style.
But many of Win32 users will want a more sophisticated library
written in C++ (or C#?).

maybe.

Jose,
I haven't answer your question on ML yet (though you probably do not
remember the question)... Currently I'm involved in a W3C related
project at Keio, and I am cooperating with the members of Keio W3C
team to develop some open source softwares, e.g. a CC/PP capable browser.

Thank you.
(sorry for my English)
