According to RFC 2616, section 3.6:
    Whenever a transfer-coding is applied to a message-body, the set of
    transfer-codings MUST include "chunked", unless the message is
    terminated by closing the connection.

libwww currently does not correctly implement the "unless" clause where
the connection is closed but a transfer-coding header is present.

Attached is a small patch which fixes this.  A URL that I've run
across that exhibit the problem with FilterProxy are:
