#66334 I found a webpage that takes about using JQuery to send a HTTP GET.

Instead of download jQuery, I included it from a CDN (Content Data Network) per the instructions at https://www.w3schools.com/jquery/jquery_get_started.asp

You may also find the information about how to set up the ESP module useful though it may have to be modified for the NodeMCU Lua.
