If either the __utmb or __utmc cookie is missing a new session is
started. The __utmb cookie expires after 30 minutes of inactivity, so
if they don't view any pages for 30 minutes a new session is started.
The __utmc cookie on the other hand is a "session" cookie in the old
fashioned sense, because it has no expiration, but is deleted by the
browser when the browser is closed.
