# Configure server and forward its output to packet cloning component
'localhost:9999' -> OPTIONS Server(sockets/tcp-server) OUT -> IN Copy(core/splitter)
# Show incoming data on the screen
Copy OUT[0] -> IN Log(core/console)
# Feedback to respond a user with what was received
Copy OUT[1] -> IN Server

$ bin/cascades run examples/tcp-server.fbp
