I've seen repeated connections from inktomi's web crawler bots, but never
at
a level that affected performance. As I remember, the inktomi bots do respect the robots.txt protocol and will go away if your system tells them to.
That has not been my experience, my test lab web server came to their crawler's attention once, almost continuously hammering away with requests for robots.txt. I had removed that file (as well as a shedload of dll's from that IIS box) when I built it but despite the continual 404's, the crawler kept hammering away, doing a nice job of filling the logs. They earned the first 'reject' rule I had implemented on the firewall ;-) And it still didn't go away... persistant little bugger, I'll say that ! I seem to recall having to go upstream for a solution as well. Regards, JJ
