Improving Scalability Through UNC-Based Centralized Content Storage

Applies To: Windows Server 2003, Windows Server 2003 with SP1

IIS 6.0 delivers several technical changes that make it easier for ISPs or other organizations to create UNC-based centralized storage solutions. Centralized content storage can make it much easier to scale your installation to thousands of Web sites. Centralized storage can also help minimize time commitments for server management and administration. This section describes the following:

  • Caching Changes. For UNC content, IIS 6.0 provides the new last-modified caching algorithm for both static and ASP files. In addition, IIS 6.0 improves the performance of change-notification-based caching for ASP files.

  • UNC Authentication. IIS 6.0 now performs UNC authentication, formerly called Passthrough authentication, by default.

  • Constrained Delegation. With constrained delegation, you can allow delegation only to certain services, so you can control the specific network resources that a service or computer can use.
