Authentication on only part of a website?

Hi there,

Is it possible to have one site (www.mysite.com) and have some pages non-password-protect and some pages password protected?

This is the tutorial I was looking at following but I can't see if there is a way to (in web config??) indicate that only some pages are to be password protected.  As an example, I have a website and of the several pages on the site, the only pages I want to be password protected are called reviewerportal.aspx, reviewerstudent.aspx, reviewerrankings.aspx.

Thanks,

Liv
