I am trying to protect my cgi scripts against spinning cpu cycles for bots. My cgi dir is in my robots.txt file, but apparently, may bots don't honor this. So, for added protection, I'm calling

%ENV{HTTP_USER_AGENT} =~ /googlebot|slurp/i

to catch all the ones from google and yahoo. This is quick and easy, but incomplete. The site www.botsvsbrowsers.com seems to have a pretty comprehensive list of known bot names, which I can easily dump into a file and build my own regex, but rather than going to all that work (that surely others have already done), I figured I'd ask if anyone's aware of something they can point me to.
