I know precisely what I'm talking about.

Still, I guess I should have been clearer - there are several "non client side" saving technologies which are outside the scope of this law, and make the law completely useless.

Further though, I would criticise the EU whatever the content of this law. We do not need a law to enforce rules about a specific technology of HTTP. What the hell business is it of the EU?

The EU is absolutely obsessed with writing up laws to invade into absolutely every area of our lives.
