What is the purpose of the addFingerPrint property in a page template definition?

I'm adding a JavaScript file to my Magnolia page template definition. For example:

jsFiles:
  index:
    link: path/to/resource.js
    addFingerPrint: true

What happens when I set addFingerPrint to true?

Solution

  • Setting addFingerPrint to true "embeds a file content fingerprint in the resource URL".

    Embeds a file content fingerprint in the resource URL. The fingerprint consists of a timestamp in the yyyy-MM-dd-HH-mm-ss-SSS format, and the word "cache" both preceded by the the standard selector ("~" tilde).
