"*Total : 20668 different pages-url*" only appears in the filtered report, but it is independant of the filtering. In fact, this information could be within the summary page.

As I wrote above, 20668 is the total number of different pages URL's in AWStats database. AWStats counted one or more hits for each of these pages.

"*67834 pages*" does not mean 67834 different pages URL's. As we know that the total number of different pages URL's for AWStats is 20668, this could be (oversimplified example) :

- 20000 pages that got 1 hit each

- 600 pages that got 5 hits each

- 67 pages that got 659 hits each

- 1 page that got 681 hits.

I agree with you that this is not presented clearly by AWStats.
