I saw a webpage in the early 2000s that when I clicked something, it remembered the data on the next pages. Think simple counter. I checked out the site and it claimed to be using something called PHP which even free hosts of the time provided. How is this not enabling right?
I had a similar "simple counter" moment at a later date and the tech was AJAX. I am yet to have a similar moment after that. Perhaps WASM based interfaces? But it's not the same. Maybe I am not the same.
