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.
