Or is it that each time a new request opens a
new connection? If so, what's the answer for 2)?
1) What's the mechanism to indicate to the server
if the client has shut down connection or not?
2) And what's | w***s

It seems that you know nothing about socket programming.
ok, normally your program will block on command 'recv' or 'recvfrom'
so, to question 1, when the client close the connection. the recv will return
0.to question 2, when data is available on socket, recv will return with the
data length and the content of the data just received.
