form authentication for sub folder

[lleemon]

Looking to make just one folder and all sub-folders within this folder to be password protected with form authentication. At this time, I have the following in my web.config file that works but it does for the whole site.
I have a folder off the root called email that calls the Login.aspx file when not authenticated. Issue is that files off the root folder are calling /email/Login.aspx as well.

Any thoughts?
