The structure of nested realms and resources used in the examples in this section are illustrated in the following diagram. The shaded areas indicate realms that are protected by an authentication scheme.
The nested realms are made up of the following directories and resources:
This directory is the top level of the sample nested realm. This realm specifies /home/ as its resource filter, and contains the unprotected resource of index.html. The index.html file is not protected by an authentication scheme.
This directory, contained in the /home directory, is protected by a Basic authentication scheme, which requires a user name and password as credentials. The realm associated with this directory uses a resource filter of employees/ and contains the employee.html file. The total Resource Filter for this realm is
/home/employees/.
This directory, contained in the /employees directory, is protected by an HTML Forms authentication scheme which requires a user name, password, and additional personal information as credentials. The realm associated with this directory uses a resource filter of managers/ and contains the manager.html file. The total Resource Filter for this realm is /home/employees/managers/.
This directory, contained in the /managers directory, is protected by an X.509 Certificate + Basic authentication scheme which requires user name, password, and a valid X509 certificate as credentials. The realm associated with this directory uses a resource filter of restricted/ and contains the restricted.html file. The total Resource Filter for this realm is /home/employees/managers/restricted/.
In these examples the protection level of the /employees realm is less than the protection level of the /managers realm, which is less than the protection level of the /restricted realm.
