# Example application that echoes read data back to the HTTP client.
# This emulates the old echo protocol people used to run.
#
# An example of using this in a client would be to run:
#   curl --no-buffer -T- http://host:port/
#
# Then type random stuff in your terminal to watch it get echoed back!
