1. Host a Web Page (index.html) via HTTP GET with 200 OK Status
2. Receive POST from that page via AJAX with browser data
3. Extract Content and Attributes
4. Build a JSON file of HTTP data
5. Store it
To accept location in a phone or modern browser you must be running SSL.
So I added that for this HTTP Request.
Use openssl to create your 2048 RSA X509, PKCS12, JKS Keystore, Import Trust Store and import in browser
Your web page can be any web page, just POST back via AJAX or Form Submit.
