I apologize for starting a new topic. It is because the subject of my
previous post does not carry any meaning to my question.
I am trying to add a new URL path (Node.js home page has given an example
to do it.) to a piece of complex existing code (shown below). The existing
code already has server configuration code but the code looks very
different from the "Building a Node.js Web Server" example that is showing
in the Node.js home page.
The new URL path is "/lens/v1/ping" that is sent from the browser window.
If that is the URL path received, I am supposed to send a response Status
200 back to the browser.
I am having difficulties to fit this new URL path and its associated code
to the existing code (show below) and I am seeking help. Thank you very
much.
