What are some effective cache-busting strategies?

Cache-busting strategies help ensure users see the latest version of your web content. Common methods include versioning your files, using query strings, and setting appropriate cache headers.

Can you explain how versioning works?

Versioning involves appending a version number to your file names, like 'style.v1.css'. When you update the file, you change the version number, prompting browsers to fetch the new file instead of using the cached version.

What about using query strings? How does that help?

Using query strings, like 'script.js?v=2', changes the URL when the file is updated. This tricks the browser into thinking it's a new resource, forcing it to download the latest version.

Are there any downsides to these strategies?

Yes, frequent cache-busting can lead to increased load times and server requests. It's important to balance freshness with performance.
