How to bypass authentication for some specific directories

[Ram, Budh]

Hi,

I am using Shibboleth SP for SSO implementation in my application (application is running on IIS7.5).
My application has two types of features 1) can be used without authentication 2) need authentication to use.
The code base for these two features is sometimes common.  Is there any configuration available in SP which allow me to bypass the idp authentication mechanism for some code directories?
If yes, then what is the configuration I need to do on SP side to access the common code directories in both cases (with/without login)?

Thanks and Regards,
Budh Ram
