* MultiHomedServers
*
* MultiHomedServers tests support for multi-homed servers, i.e. a distinct web servers on each IP interface.
* It only tests the case n=2 because on a basic ESP32 device, we only have two IP interfaces, namely
* the WiFi station interfaces and the WiFi soft AP interface.
*
* For this to work, the WebServer and the WiFiServer classes must correctly handle the case where an
* IP address is passed to their relevant constructor. It also requires WebServer to work with multiple,
* simultaneous instances.
*
* Testing the WebServer and the WiFiServer constructors was the primary purpose of this script.
* The part of WebServer used by this sketch does seem to work with multiple, simultaneous instances.
* However there is much functionality in WebServer that is not tested here. It may all be well, but
* that is not proven here.
*
* This sketch starts the mDNS server, as did HelloServer, and it resolves esp32.local on both interfaces,
* but was not otherwise tested.
*
* This script also tests that a server not bound to a specific IP address still works.
*
* We create three, simultaneous web servers, one specific to each interface and one that listens on both:
*
* name IP Address Port
* ---- ---------- ----
* server0 INADDR_ANY 8080
* server1 station address 8081
* server2 soft AP address 8081
*
* The expected responses to a brower's requests are as follows:
*
* 1. when client connected to the same WLAN as the station:
* Request URL Response
* ----------- --------
* http://stationaddress:8080 "hello from server0"

Have a FAT Formatted SD Card connected to the SPI port of the ESP8266
The web root is the SD Card root folder
File extensions with more than 3 charecters are not supported by the SD Library
File Names longer than 8 charecters will be truncated by the SD library, so keep filenames shorter
index.htm is the default index (works on subfolders as well)
upload the contents of SdRoot to the root of the SDcard and access the editor by going to http://esp8266sd.local/edit
To retrieve the contents of SDcard, visit http://esp32sd.local/list?dir=/
dir is the argument that needs to be passed to the function PrintDirectory via HTTP Get request.
