What are some examples of cache control headers?

Cache control headers are used to specify directives for caching mechanisms. For example, 'Cache-Control: no-cache' means the browser must revalidate the resource with the server before using a cached copy.

Can you give me more examples?

Sure! Here are a few more:

1. 'Cache-Control: max-age=3600' - The resource is fresh for 1 hour.
2. 'Cache-Control: public' - The response can be cached by any cache.
3. 'Cache-Control: private' - The response is intended for a single user and should not be stored by shared caches.

What does 'must-revalidate' mean?

'must-revalidate' means that once a cached response becomes stale, it must be revalidated with the origin server before being served to the user.

How do these headers affect website performance?

Proper use of cache control headers can significantly improve website performance by reducing load times and server requests, leading to a better user experience.
