# Test code:
# $ echo hello $(date) | nc -u 127.0.0.1 5005
# $ echo hello $(date) | nc -u 127.0.0.1 5005
#
# If it's connection_oriented, only the first hello will work because it's bound to a soruce ip + port
# pair and re-running the command runs with a different source port.
# You'll need to restart the app or disconnect the socket to get data from a new connection.
