[ic] Just upgraded 4.8.9->5.2 - RobotUA question

[DB]

I just upgraded by foundation based catalog from 4.8.9 to 5.2.0. I 
followed the UPGRADE file instructions and things went pretty smoothly. 
My main reason for the upgrade was to take advantage of the RobotUA feature.

After the upgrade, I added the section below to the end of my 
interchange.cfg, however I still entries like this in my apache access_log:

"GET /unlisted.html?id=gAW3nswb HTTP/1.0" 200 17202 "-" "ia_archiver"
"GET /helpfaq.html?id=SRvEvzVq HTTP/1.0" 200 32017 "-" "msnbot/0.3 
(+http://search.msn.com/msnbot.htm)"

Now I thought the RobotUA prevented spiders from obtaining session ids? 
Am I confused, or can someone tell me why these spiders appears to be 
still obtaining session ids?

Here's what I added to my interchange.cfg, and yes I did restart :) 
Thanks for any input. - DB
