Implementing Forms-Based Authentication

[Antedymed]

I have a website for public users, but also have an admin part of about 10 pages, that I need to secure for website admin only.If I implement Forms-Based Authentication on the 10 pages, will it also spread across the public part of the website too? i.e. changes in web.config.I was looking at this example (http://support.microsoft.com/kb/301240) but it looks like it closes off public view for entire application!?!RegardsTea
