/**
Example for the WT32_ETH01 HTTP(S) Webserver
IMPORTANT NOTE:
To run this script, your need to
1) Make sure to have certificate data available. You will find a
shell script (create_cert.sh) and instructions to do so in the library folder
under extras/
This script will install an HTTP Server on port 80 and an HTTPS server
on port 443 of your WT32_ETH01 with the following functionalities:
- Show simple page on web server root
- 404 for everything else
The comments in this script focus on making both protocols available,
for setting up the server itself, see Static-Page.
