What is CDN, and how does it work?
Date30 Aug 2022
- When a visitor requests website content, the origin or main server gets the request.
- The main server responds to the user directly and sends a replica of the answer to the CDN PoP that is nearest to the user’s location
- The CDN PoP registers the copy of the response in the form of a cached document.
- When the user requests the same website content the next time, the caching server responds instead of the origin or main server.
