Webserver example for Nuvoton NuMaker boards and mbed OS 5.15 - HTTP 1.1 and multi-threaded.
For Mbed OS 6, please use the NuMaker-simple-httpd example.
This application demonstrates how to run an HTTP server on an mbed OS 5 device. It is derived from http-webserver-example Request parsing is done through nodejs/http-parser.
Fixed for Mbed OS 5.15 or later
Tested on
NuMaker IoT-M487 with Ethernet NuMaker PFM-M487 with Ethernet
