What are the different cache-busting techniques I can use for my website?

Cache-busting techniques help ensure users see the latest version of your website. Common methods include adding version numbers to file names, using query strings, and setting cache-control headers.

Can you explain how adding version numbers works?

Sure! By appending a version number to your file names, like 'style.css?v=2', browsers will treat it as a new file, forcing them to fetch the latest version instead of using the cached one.

What about using query strings? Is that effective?

Yes, using query strings is effective! Similar to version numbers, adding a query string like 'script.js?ver=2023' changes the URL, prompting the browser to load the new file.

Are there any downsides to these techniques?

One downside is that frequent cache-busting can lead to increased load times as users may have to download new files more often. It's important to balance freshness with performance.
