khoih-prog:
IMHO, this is just a small issue, and can be fixed quickly by modifying the lib.
How about your taking over the super Arduino WebServer lib?
I have already too many Arduino plans. this one was behind the horizon.
for example today I added to my todo list "improve ArduinoHttpClient library". it uses only int for contentLength and doesn't support F().
yesterday I finished OTA download examples.
It would be good to finish/make OTA for Nano 33 BLE, Nano every, STM32
Two projects are waiting...
