# example program: a single-request HTTP server
#   listen for connections from clients on a server socket
#   when a connection occurs, transfer it to a session socket
#   read from it using channels
#   write to it directly
#
# After running it, navigate to localhost:8080. Your browser should display
# "SUCCESS!" and the server will terminate after one connection.
