How can I force the web browser to do a hard refresh of the page via JavaScript?
Hard refresh means getting a fresh copy of the page AND refresh all the external resources (images, JavaScript, CSS, etc.).
CMS
Try to use:
location.reload(true);
When this method receives a true value as argument, it will cause the page to always be reloaded from the server. If it is false or not specified, the browser may reload the page from its cache.
More info:
window.location.href = window.location.href
