From your question, I am assuming you want to dig more into the difference between Ajax Polling & Long Polling.

With regards to that -

This W3School resource is a good read on understanding how Ajax code works

To understand how long polling works? Do go through this StackOverflow thread - How Long Polling Works?

Also, read Ajax Polling Vs Long Polling

If it’s something else let me know.
