ASP.NET Forms Authentication - non standard scenarios supported?

[Jeff]

Can ASP.NET Forms Authentication be used to control access to a single ASPX
page based on querystring parameters? For example, consider a frameset used
to display a database-driven photo album. Multiple different "albums" in
this scenario are displayed using the same pages - and differ simply in the
content displayed (and the specific content displayed is controlled by the
querystring parameters). Can I use ASP.NET Forms authentication to require
authentication in order to veiw certain "albums" even though all albums are
presented using the same aspx pages? Or do I have to "roll my own" on this
scenario?

Thanks.
