What are common mistakes with caching headers?

What are common mistakes with caching headers?

Common mistakes include not setting cache-control headers, using incorrect max-age values, and failing to validate cached content.

Can you explain what cache-control headers are?

Cache-control headers dictate how, and for how long, browsers and other caches should store responses.

What happens if I don't set any caching headers?

If no caching headers are set, browsers may not cache the content, leading to slower load times and increased server load.

How can I test if my caching headers are set correctly?

You can use browser developer tools or online tools like WebPageTest to inspect the response headers.
