/**

* Example for the ESP32 HTTP(S) Webserver

* IMPORTANT NOTE:

* To run this script, your need to

* 1) Enter your WiFi SSID and PSK below this comment

* 2) Make sure to have certificate data available. You will find a

* shell script and instructions to do so in the library folder

* under extras/

* This script will install an HTTPS Server on your ESP32 with the following

* functionalities:

* - Show simple page on web server root

* - 404 for everything else

* The server will be run in a separate task, so that you can do your own stuff

* in the loop() function.

* Everything else is just like the Static-Page example
