RE: Identifying Known Spiders?

The robots list from which that page was built no longer exists. The group that was maintaining it decided that it didn't make sense to maintain a database of "known robots" any more as anyone can make a robot. However, some quick review looks like there's a new user-submitted list at http://www.robotstxt.org/db.html and a "wild caught" list at http://www.botsvsbrowsers.com/category/1/index.html. If I have time this weekend, maybe I'll update the scripts to pull from one of those sources.

I have to say though, that the more I think about it, the more I'm of the mind set that anything that is *not a known web browser* is most likely a bot. And maybe inverting the logic would make sense at this point.

No, the only special treatment for spiders in Analog is the ROBOTINCLUDE
command which tells Analog to count the requests with the specified
User-Agents as Search Engines in the OS Report.

There used to be a list of Spider User-Agents at
http://www.wadsack.com/robot-list.html but it seems to be empty at the
moment. There's a list from may 2007 at
http://www2.owen.vanderbilt.edu/mike.shor/diversions/analog/RobotInclude.txt

You might want to do a report with FILEINCLUDE /robots.txt, which should
give you a good indication of which search engines are hitting your site.
