Just to clarify... .htaccess can also redirect and not just block content.
http://httpd.apache.org/docs/current/mod/mod_rewrite.html
It could be used to block or just redirect bad guys to a logging page,
suspected bad guys to a limited site index and all others to your
regular site.
That's all. I'll shut up about apache now. :)

Quick glance I'd say
listFindNoCase(searchTermList,cgi.http_user_agent). Put the search
terms in a list to find.
This will only work if the entire exact case-less user agent matches
an item in the list. I don't think it will solve Derrick's
problem. listFindNoCase('badbot version
30','badbot,jokerbot,sillybot') will return false.
In a perfect world, I second Mark's suggestion of .htaccess.
The further up the stack you can move this, the better. Move it all
the way to the firewall if you can. Takes load off the CF engine.
I'm not sure that works for you either though, since you aren't
blocking them, sounds like you are just modifying the session timeouts
and such on those requests.
I think looping over the values in CF is probably your best option.
Looping over a list, or converting that list to an Array and caching
the array might be slightly faster. I wouldn't be too worried about
speed unless it's deemed a problem. Almost certainly there is another
bottleneck worth fretting over more than the 10ms a list loop might be
adding to each request.
List loops do get increasingly slower the longer they get because of
the way CF parses lists though, So keep it in the back of your mind
for a future optimization. You know, like when they list reaches a
few hundred items, or you are getting a billion pageviews a day.
I remember Hal Helms saying the three laws of optimization during an
ACFUG meeting years ago:
1) Don't optimize yet
2) Don't optimize yet
3) Don't optimize yet
