It sounds like you want to allow access for bots without authentication, while still requiring humans to authenticate for the same URL. That can't be secure. A human could impersonate a bot.
On the other hand, if you want to authenticate just the 20% of the site that you don't need the bots to access, you could use the url-pattern on the CAS filter in web.xml (with the Java client, at least).
