How can I optimize my API caching strategy?

To optimize your API caching strategy, consider using cache headers effectively, implementing cache invalidation, and choosing the right caching layer.

What are cache headers and how do they work?

Cache headers are HTTP headers that control how responses are cached by browsers and intermediate caches. They include directives like 'Cache-Control' and 'Expires'.

Can you explain cache invalidation?

Cache invalidation is the process of removing or updating cached data when the underlying data changes, ensuring users receive fresh data.

What caching layers should I consider?

You can consider using in-memory caches like Redis, CDN caching for static assets, and reverse proxies like Varnish for dynamic content.
