User agent

Requests from Yahoo! Slurp carry user agents like these:

Mozilla/5.0 (compatible; Yahoo! Slurp China; http://misc.yahoo.com.cn/help.html)

Mozilla/5.0 (compatible; Yahoo! Slurp; http://help.yahoo.com/help/us/ysearch/slurp)

Mozilla/5.0 (compatible; Yahoo! Slurp/3.0; http://help.yahoo.com/help/us/ysearch/slurp) NOT Firefox/3.5

Device Detector identifies it with this pattern (a case-insensitive regular expression):

Yahoo! Slurp|Yahoo!-AdCrawler

Anyone can put any name in a user agent. Where the operator publishes IP ranges, checking the request's address against them is the way to confirm a visit is genuine.

How Vireo counts Yahoo! Slurp

Vireo keeps requests from Yahoo! Slurp out of your pageviews and visitors and counts them on its bot report under Search engines, so you can see how much it left out rather than wonder why your server logs show more traffic.

Checked by running Vireo Analytics' own bot filter over Yahoo! Slurp's user agents.
