Only for those connections where the client actually asked for the
connection to stay alive after the response has been sent.  Otherwise
no.

Each request is handled independantly.  If a keep-alive is not used on
one request, then that connection will be disconnected after the
response is sent.  The client would then have to reconnect to send the
next request.

Then the client is going to have to reconnect on each new request.

Then the client is likely not requesting a keep-alive in its request
to begin with, so the server's KeepAlive option is ignored for that
connection.
