What are the different cache control header directives?

Cache control header directives are used to specify caching policies in HTTP responses. They help control how, and for how long, browsers and other caches store responses.

Can you explain some common directives?

Sure! Some common directives include 'no-cache', which forces caches to submit requests to the origin server for validation, and 'max-age', which specifies the maximum amount of time a resource is considered fresh.

What does 'public' and 'private' mean in this context?

'public' means the response can be cached by any cache, while 'private' indicates that the response is intended for a single user and should not be stored by shared caches.

How do these directives affect performance?

Using cache control directives effectively can significantly improve performance by reducing load times and server requests, leading to a better user experience.
