Webserver example for Nuvoton NuMaker boards and mbed OS 5.15 - HTTP 1.1 and multi-threaded.

Dependencies:   mbed-http

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

+# mbed-os-example-http-server
+
+This application demonstrates how to run an HTTP server on an mbed OS 5 device.
+
+Request parsing is done through [nodejs/http-parser](https://github.com/nodejs/http-parser).
+
+## To build
+
+1. Open ``mbed_app.json`` and change the `network-interface` option to your connectivity method ([more info](https://github.com/ARMmbed/easy-connect)).
+2. Build the project in the online compiler or using mbed CLI.
+3. Flash the project to your development board.
+4. Attach a serial monitor to your board to see the debug messages.
+
+## Tested on
+
+* K64F with Ethernet.
+* NUCLEO_F411RE with ESP8266.
+    * For ESP8266, you need [this patch](https://github.com/ARMmbed/esp8266-driver/pull/41).
+
+But every networking stack that supports the [mbed OS 5 NetworkInterface API](https://docs.mbed.com/docs/mbed-os-api-reference/en/latest/APIs/communication/network_sockets/) should work.
