# MicroPython http_server_simplistic.py example
#
# This example shows how to write the smallest possible HTTP
# server in MicroPython. With comments and convenience code
# removed, this example can be compressed literally to ten
# lines. There's a catch though - read comments below for
# details, and use this code only for quick hacks, preferring
# http_server.py for "real thing".

# interfaces to let this example work easily on embedded MicroPython
# targets, which you will likely access from another machine on your
# local network. Take care when running this on an Internet-connected

# data size. That's why this example is called "simplistic" - it
# shows that writing a web server in Python that *usually works* is
