There is a really good article out on DZone covering the ways to set up NGINX for caching, reducing latency and load.
Well worth a read, especially if you want to take advantage caching without needing to rewrite or change code. Covers basic configs, monitoring concepts as well as things to watch out for.
This quote really says it all:
“When latency matters, reliability is critical, and scale is inevitable, NGINX caching becomes more than a convenience — it becomes a necessity.”
