I have recently redesigned my web site, and have been monitoring search engine crawls to ensure that they are being redirected properly, and have started seeing odd requests from Yahoo's SlurpBot. The request details are as follows:
IP Address: 66.196.91.120
User Agent: Mozilla/5.0 (compatible; Yahoo! Slurp;
http://help.yahoo.com/help/us/ysearch/slurp)
Request: /SlurpConfirm404/
randomword/pathtopagethatusedtoexist.html
What has me especially confused is, because of the random word, which is different in each request, as well as the SlurpConfirm404 portion, there is no way that the page they are trying to retrieve could exist, so what is Yahoo looking for?
