问题 I'm new to HTML5's application cache, but am familiar with the basics of it. I'm working on a cache manifest file for a SilverStripe site that needs to be dynamically updated whenever the content manager uploads a new image. I understand that the images will be appended to the Manifest function below using a loop, but the part that I find to be a challenge is updating the date and version number every time.
