- Lornedon 3y agoSorry, I sent my comment before it was done. It's edited now.
- Akronymus 3y agoYeah, I see your edit. With JS you can also detect whether it was fetched before, so that is a way of storing information about whether you have visited something before. Which can then be sent to the server. So, it kinda is storing data, kinda not.
