// `wget` sends an HTTP/1.0 request with Connection: Keep-Alive
//
// Sending back a chunked response to an HTTP/1.0 client would be wrong,
// so what has to happen in this case is that the connection is closed
// by the server after the entity body if the Content-Length was not
// sent.
//
// If the Content-Length was sent, we can probably safely honor the
// keep-alive request, even though HTTP 1.0 doesn't say that the
// connection can be kept open.  Presumably any client sending this
// header knows that it is extending HTTP/1.0 and can handle the
// response.  We don't test that here however, just that if the
// content-length is not provided, that the connection is in fact
// closed.
