    The response should contain status=400, reason="Bad request", as
per RFC2616 section-10.4.3. The server may add some HTML page to explain
it to the human user of the client.

    Then the sever should find a way to flush the rest of the input and
wait for the next request. The only way I know to flush for sure the
rest of the input is to disconnect.
