The difference between Total Requests and Unique Requests on NxFilter reports.

[support200]

There are Total Count and Unique Count for NxFilter reports. The difference between Total and Unique is from NxFilter's logging system. To reduce the amount of disk access, NxFilter keeps all the log data in its memory space before it flushes out the data once a minute. If there is a request for the same domain from the same user in a minute, it only increases the count for the data. So, Total means the sum of all the requests and Unique means the count for all the unique data.
