What are the different Cache-Control directives?

What are the different Cache-Control directives I should know about?

Cache-Control directives are HTTP headers that control how caching is handled in web browsers and servers. Some key directives include 'no-cache', 'no-store', 'public', 'private', 'max-age', and 'must-revalidate'. Would you like to know more about any specific directive?

Can you explain what 'no-cache' means?

Certainly! The 'no-cache' directive tells the browser that it must revalidate the resource with the server before using a cached copy. This ensures that the user always gets the most up-to-date version.

What about 'max-age'? How does that work?

'max-age' specifies the maximum amount of time a resource is considered fresh. For example, 'max-age=3600' means the resource can be cached for one hour before it needs to be revalidated.

Are there any other important directives I should be aware of?

Yes, 'public' and 'private' are also important. 'public' allows the response to be cached by any cache, while 'private' restricts caching to the user's browser only.
