Cache buster is a technique used to ensure that the browser loads the latest version of a file. It is commonly used to bypass browser caching and force the user to download the latest version of a file or webpage. This is particularly useful when there are updates or changes to the content that need to be immediately visible to the user.

  • How it works:

    • It typically involves appending a unique query parameter to the URL, such as a timestamp or a random string.
    • When the user requests the file or webpage, the browser checks for this parameter and, if present, fetches the latest version.
  • Why use it:

    • To ensure that users always see the most up-to-date content.
    • To prevent users from viewing outdated information.
  • Example:

    • Suppose you have a webpage at https://example.com/page.
    • To implement cache buster, you could modify the URL to https://example.com/page?cb=<timestamp>, where <timestamp> is a unique identifier.
