yes.  What I want is that, server sends response to client and closes
connection when it feels recieving enough information, and make sure
at the same time ,client will definitely get the response from server.

as I saied before,  running results will varies. And most of the time
they are working quite well. But that's not enough.

This really helped.
Now I know the client will still get the response even under
'Connection reset by peer' or 'Broken pipe'.
