How does cache busting improve performance?

What is cache busting and why is it important for web performance?

Cache busting is a technique used to force browsers to load the latest version of a resource, like CSS or JavaScript files. It's important because it ensures users see the most up-to-date content, improving their experience.

How does cache busting actually improve loading times?

By preventing outdated files from being served, cache busting reduces the chances of users encountering errors or seeing old content. This leads to faster loading times as the browser fetches the latest resources.

Are there different methods for implementing cache busting?

Yes, common methods include appending version numbers or hashes to file names, or using query strings. Each method has its pros and cons depending on the project.

Can cache busting negatively impact performance?

If not managed properly, cache busting can lead to increased server requests and longer loading times, especially if resources are frequently changed without proper versioning.
