Apply this Action to the site folder, or to a page. It will seek out as many <link> and <script> tags that it can find, and append a “?v=x” to the end, where x is a number.
To force a new versuon to be loaded, click the Renew Version button in the Actions Palette. This will dirty the page (or site if you are using it on a folder). Next time the site is published, a new version number is appended to the file, and that shiuld trigger a re-load in any browser.
Note: for this Action to work, the refrebnces to CSS and JavaScvript files must be part of the tag stream. If it’s been put in as part of a mark-up item, the Action will not process it.
