difference in the use of get, http 1.0 and 1.1

you are implying because
client.println("GET / HTTP/1.0\r\nHost: www.eeteam.net\r\n\r\n");
sends one packet, it won't work?

the w3c spec gives a more "authoritative" explanation on why sending the extra \r\n is needed. It has nothing to do with packets.
