What are the best practices for browser caching?

The best practices for browser caching include setting appropriate cache headers, using versioning for assets, and leveraging cache busting techniques.

Can you explain what cache headers are?

Cache headers are HTTP headers that control how and for how long browsers cache your content. Common headers include 'Cache-Control' and 'Expires'.

How does versioning work for assets?

Versioning involves appending a version number or hash to your asset URLs, so when the asset changes, the URL changes, prompting the browser to fetch the new version.

What is cache busting?

Cache busting is a technique used to force browsers to load the latest version of a resource, often by changing the URL or query string.
