Hmm, you are going through an internal proxy which is a netscape proxy
3.5.2. Some times, it seems to return a 500 Internal error message, see the
clip below. It seems that it doesn't send the right amount of bytes and
then libwww aborts the operation. This may not be a libwww problem but a
proxy problem.
