HTTP is stateless protocol. There is no such thing as close (or open). The only thing anywhere like a duration in it is the time it takes to deliver the message bytes and request-response latency. If you try to use that you will find that users spend an *extremely small* amount of time visiting URLs. The vast majority of time is spent elsewhere doing things with the response objects. Semi-reliable user tracking was possible back in the 1980-1990s - though the coffee problem has always been an issue. But with the invention of multiple-windows on a screen, and more recently tabbed browsing the ability to guess offline activity for page A vs page B is much reduced. I know there are lots of companies etc out there saying they can track user activity for third-party sites. They are lying-by-omission, at most they are tracking the activity of some marker which may (or may not) actually be representing "a user" through some series of message transactions. It always comes down to somebody making a guess about whether any two requests are related.
