Cache Busting

Cache busting is a technique used to ensure that users receive the most recent version of a website’s files, like images or scripts, instead of outdated ones stored locally in their browser’s cache. When updates are made, cache busting appends a unique identifier (such as a version number or timestamp) to file URLs. This makes the browser treat the files as new, prompting it to download the latest version. It helps prevent issues where outdated files cause website functionality or appearance problems, ensuring users see the most current content without manual cache clearing.
