New crawler version using cookies?

Yahoo Vertical Crawler

[misja]

Hi,

Is this a new crawler?

Yahoo-VerticalCrawler-FormerWebCrawler/3.9 crawler at trd dot overture dot com; [alltheweb.com...]

This crawler uses cookies.

The old FAST-WebCrawler/3.8 is also visiting my site at the same time AFAIK that one doesn't use cookies.

Yep, it looks new to me, and yep, it uses cookies. Unfortunately, it doesn't seem to use robots.txt.
