Deciphering AEM Cache Puzzle: Browser, CDN (Revalidation), and Dispatcher by Aanchal Sikka

Overview

Caching & Revalidation: how do these mechanisms work together between browsers, CDNs, Dispatcher and AEM to ensure fast content delivery across the globe.

In this blog, I have shared:
- The roles of each player in the AEM content delivery chain
- How caching and revalidation work to optimize performance (with scenario-based examples).

Very well written and highly insightful! Thanks @aanchal-sikka! 
One query - For AEMaaCS does Adobe provide a mechanism to clear cache explicitly for a URL on Fastly/CDN?

Adobe can flush the entire cache if requested via Support Ticket. But, they also provide a curl command for flushing individual resources. ExampleL https://experience-aem.blogspot.com/2023/01/aem-cloud-service-invalidate-dispatcher-purge-fastly-cdn...

The API key would have to requested from Adobe via Support ticket.
