How do I implement cache control headers?

How do I implement cache control headers in my web application?

To implement cache control headers, you can set them in your server's response. For example, in an Express.js app, you can use res.set('Cache-Control', 'public, max-age=3600');.

What do the different directives in cache control mean?

The directives specify how caching should be handled. For instance, 'public' means the response can be cached by any cache, while 'max-age=3600' indicates the response is fresh for 1 hour.

Can I set different cache control headers for different file types?

Yes, you can set different headers based on file types. For example, you might want to cache images longer than HTML files.

How can I test if my cache control headers are working?

You can use browser developer tools or tools like cURL to inspect the response headers and verify the cache control settings.
