Why do you need to put a big libwww layer inbetween there? Is it impossible
to filter the data directly?

If the requests made by the user to the personal firewall and the requests 
made by libwww to the net are not directly correlated, I think you'll need 
to run libwww in a separate thread so it can download whatever it needs, 
and then somehow send the data to the callback.

I don't think you need a full HTTP server here - can't your callback code
just use libwww like any other client?

I'm not sure - I guess you could make it behave like a HTTP proxy with some
work, but I don't really understand why you'd want to use it that way. :)

IMHO, the only code with comparable functionality is the one in Mozilla. 
(Dunno about Konqueror, does it support HTTP pipelining?) But there's also
libcurl, which is simpler, cleaner and easier to use.

No - use the source, Luke! ;-)
