No, otherwise it would abort the server's response. It's doing a shutdown(SHUT_WR), which results in a FIN on the wire. Anyway, as of 1.4 we don't do that anymore since we're aware of the end of response. So we close the connection as soon as we get the whole response from the server and here yes, we close with an RST (at least we try to do so, since we don't control this).

It depends what version you're reading :-)
