A user-agent SHOULD (per the RFC) provide a Content-Length header,
but it's not *required*, nor if it exists can you count on it being
accurate :-)

And if, at the point the header is available, you read it and close
the connection, there will still have already been a lot of data on
the wire, so bandwidth will have been (pointlessly) consumed, which
appeared to be the original concern.
