URL, the time spent by each user on that specific URL.
To calculate the time spent, AsyncOS assigns each active user with 60
seconds of time for activity during a minute. At the end of the minute, the
time spent by each user is evenly distributed among the different domains
the user visited. For example, if a user goes to four different domains in an
active minute, the user is considered to have spent 15 seconds at each
domain.

AsyncOS defines a page view as an HTTP request initiated by the user,
as opposed to a request initiated by the client application. AsyncOS
uses a heuristic algorithm to make a best effort guess to identify user
page views.
