Hiya, When a client sends an UDP datagram to an UDP server, the connection is ESTABLISHED when the server sends back an UDP datagram and the client sends another UDP datagram or does the connection is ESTABLISHED when the server answer to the first UDP datagram ? For example, is it like that : Client -> DATA -> Server Client <- DATA <- Server Connection ESTABLISHED for the server ! Or Client -> DATA -> Server Client <- DATA <- Server Client -> DATA -> Server Connection ESTABLISHED for the server ! Thanks, -- -- Eddahbi Karim Phone : (33) (0)6 61 30 57 77 France
