What are the best practices for Cache-Control directives?

The best practices for Cache-Control directives include setting appropriate max-age values, using public or private directives wisely, and considering the use of no-cache for sensitive data.

Can you explain what max-age means?

Max-age specifies the maximum amount of time a resource is considered fresh. After this time, the resource is considered stale and must be revalidated.

What is the difference between public and private directives?

Public directives allow the response to be cached by any cache, while private directives indicate that the response is intended for a single user and should not be stored by shared caches.

When should I use no-cache?

Use no-cache when you want to ensure that the cached response is revalidated with the origin server before being served to the user.
