-  AsyncCustomHeader_STM32_LAN8720.ino - Dead simple AsyncHTTPRequest for ESP8266, ESP32 and currently STM32
-  
-  For ESP8266, ESP32 and STM32 with LAN8720 or built-in LAN8742A Ethernet (Nucleo-144, DISCOVERY, etc)
-  
-  AsyncHTTPRequest_Generic is a library for the ESP8266, ESP32 and currently STM32 run built-in Ethernet WebServer
-  
-  Based on and modified from asyncHTTPrequest Library (https://github.com/boblemaire/asyncHTTPrequest)
-  
-  Built by Khoi Hoang https://github.com/khoih-prog/AsyncHTTPRequest_Generic
