Klatt on 90sAREover's user agent

Here are pages 1633-5 of Richard Warman and the Canadian Human Rights Tribunal v. Marc Lemire (T1073/5405 vol. 9) of Feb. 8, 2007. In it, Lemire's expert witness, Bernard Klatt, is testifying about the logs of Lemire's site, and trying to make the case that "90sAREover" was identical to "lucy" (a username of Richard Warman). 

In the following passage, Klatt describes a few of the log-entries.  He has already pointed out that "90sAREover" and "lucy" share the same IP:, but as we've seen elsewhere, this does not prove they were identical: that IP is a proxy shared by hundreds of thousands of Rogers' customers.  Below Klatt describes other facts found in the entry:

p. 1633

p. 1634

p. 1635
Now, to judge from Klatt's remarks here, the log entry, which will have ended with user-agent data, must have looked something like this:
     "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; Rogers Hi-Speed Internet; (R1 1.3))"
This is something that we have paralleled in weblogs elsewhere.  This exact same configuration can be found in this log of June 4, 2004, of the Engineering School at the University of Illinois.  The date of that log rather spoils Klatt's theory that this is a firmware update from Cisco.  There is a better explanation that we'll return to in the next post.

Update As you can see from the actual logs (which can be perused in my post on the Klatt affidavit in Warman v. Lemire), the conclusion reached above is correct and 90sAREover's user agent string was follows: "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; Rogers Hi-Speed Internet; (R1 1.3))". Since this is different from the set-up used by Warman in October and November, the posts were made from different computers.
