Are these answers the same as of 2025? I do not have server-side configuration control on my Bluehost account, but I can change my html and other files on the server as needed. I don't want users to have to refresh pages manually (some are in their 80s). I also have links to PDF files, which users have had to refresh to see the latest version that I have uploaded to the website. So I need an updated answer to stop client-side caching of pages.
