We have certain pages that get updated often. However, the images are cached and sometimes, the old banners/images are the ones being viewed by some people. This is crucial because some of the banners contain 1-day promotions. If the older images are the ones being viewed, then we aren’t able to communicate to them about the promotion.
This also happens to CSS. Sometimes, we update the CSS but even after a couple of refreshes, the old CSS is still the one being loaded.
Is there a way to prevent these from happening?
