The cookie is valid at 0. if the cookie still exists after it is opened in the original browser due to unexpected circumstances (such as power failure or process termination ),
This assumption does not exist!

The buffer zone is written only when the cookie is valid more than the current time and has left the current website.

Is there a way to achieve this? Setting a cookie has an effect. can I clear the cookie by turning it off the browser? otherwise, I will not clear the cookie?

If the validity period is 0, it will not be saved.
