+/**
+ * Very slightly more complex than example1. The only thing this does
+ * differently is introduce a loop into the response, so you don't
+ * have to restart the program after one response. Also, it prints
+ * out the socket pair the server sees. Run the program via telnet
+ * several times and compare the socket pairs.
+ * 
+ * <code>telnet localhost 2317</code>
+ * 
+ * If you're sophisticated you can contact the instructor's computer
+ * while running this program.
+ * 
+ * <code>telnet ipOfServersLaptop 2317</code>
+ * 
+ * And have that machine display the socket pairs received.
