Newbie: simple asp security form with CAPTCHA

I've created a simple form that creates a .csv and will generate an
email (intro.asp).
For some security, I've been asked to include CAPTCHA. I found Web Wiz
CAPTCHA and it works fine -- I have a name text field and the CAPTCHA.
A correct response redirects to the full form's page, with more text
fields (survey.asp).
There's no login/password, but I'm concerned that bots will circumvent
the intro.asp page and go directly to the survey.asp page.
I'm pretty sure that what I need is a session variable somewhere in
survey.asp and following pages to prevent pages from being viewed out
of sequence.
Unfortunately, I don't know how that session variable is constructed.
Help much appreciated.

Please don't multipost. This question has nothing to do with databases so
posting it here served no purpose.
