For example, when a user clicks a link from a website, they are first redirected to an intermediate tracker site and then to the target site.

• When calculating the cookie lifespan (expire attribute), it now takes into account server time (if known): the difference between local and server time is added, and if the local time is ahead of the server time, cookies are considered valid if they have not 'expired' according to server time.
