|
* 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
