  the amount of traffic they have downloaded from
  the Inter net in the past 14 days. Users that
  download a large amount will have their access
  slowed, or even denied. Users who are not
  explicitly listed in this report have downloaded
  less than 1 MB/day and fall into the no delay
  category. Totals are recalculated regularly, and
  delays are automatically enforced,

This is the current configuration for our
user-based web quotas. There are similar config
file entries for other types of quota.
