Redirecting an Unauthenticated Request
Using the forms authentication scheme, an unauthenticated request to a protected server resource results in the user being redirected to a default login page. Alternatively, you can redirect the user to a target of your choosing, whether it is a custom login page or a page that provides unprotected content.
To redirect an unauthenticated request to a different page
1. As system administrator, click Administration > Folders > System > Authentication Schemes.
2. Click the Tools icon 
for the default authentication scheme, and then click Properties. By default, the forms authentication scheme redirects unauthorized requests to the default login page. You can verify that an authorization scheme is the default by looking at the Properties page. The Aliases list contains the auth.scheme.default alias.
3. In the Performs Redirect list of the Properties page for the authentication scheme, make sure Yes, this performs a redirect is selected.
4. Under Redirect URI, do one of the following:
