Indeed, mostly if the content is small, it is completely sent in http_recv()/http_send()/http_eof()/http_close_conn()/http_close_or_abort_conn()/http_state_free()/fs_close()/fs_close_custom().
tcp_write() is called in http_write() without TCP_WRITE_FLAG_COPY, at least it seems so to me. If I understood well, this means the content isn't copied in another buffer, so it *will* be sent from the original *dynamic* buffer. When fs_close_custom() is called, the content is pushed in the output queue, but it isn't actually sent over the wire.
So is it correct to free the dynamic buffer in fs_close_custom()?
