Newbie cloaking primer [webmasterworld.com]

Another cloaking how-to-do primer [webmasterworld.com].

And some cloaking FAQ [webmasterworld.com].

does code also include every ip of every SE spider?

How about maintaining a complete up-to-the-minute IP database, including the ones they sneak out to catch you.

am wondering if my current script is correct or not....

Try it out, like on a spare domain. Make two pages that are substantially the same, including graphics, with very minor differences that only you know will be there, like a minor insignificant wording change: one for your browser and the other for spiders. That doesn't mean you'll have all the IP numbers you need, but it's a start.

Disclaimer: I don't know anything but the risk and some common sense. Cloaking has never been an option for me; if I don't keep up with doing my dishes, I certainly wouldn't keep up with spiders, and that's a recipe for disaster.
