www.w3.org is an Apache (Jigsaw was not that stable for a big site at
that time), but jigsaw.w3.org is (running on an old and small solaris2.5
box). Apache, as it doesn't have a global view of connections (forked
process and not threads) it has a very short timeout on persistent
connections. I suspect that the close of the stream must trigger some
action in IE (1.0 like), and it is not happening using Jigsaw, as the
timeout is quite long (more than 30mn by default if my memory is good).
If you got the problem on Apache also, then it still may be the 1.1
replies.

One workaround maybe the following (roughly)

outGoingFilter (Request req, Reply per) {
if (req.getUserAgent() == IE4)
   reply.setKeepConnection(false)
}

and to have this filter on the protocol frame of the root resource.
But it is a dirty hack :)
