  What’s New in the Web Server (IIS) Role (IIS 7)

  What are the major changes?

  Many features have been added or enhanced in Internet Information Services (IIS) 7.5, which is the foundation of the Web Server role in Windows Server® 2008 R2.

  The following changes are available in the Web Server (IIS) role in Windows Server 2008 R2:

  Integrated extensions

  WebDAV and FTP

  Request Filtering

  Administration Pack modules

  Management enhancements

  Best Practices Analyzer

  Windows PowerShell™ Provider and cmdlets

  Configuration logging and tracing

  Application hosting enhancements

  Service hardening

  Managed service accounts

  Hostable Web Core

  Failed Request Tracing for FastCGI

  Enhancements to .NET support on Server Core

  Integrated extensions

  Building on the extensible and modular architecture introduced with IIS 7.5, the new IIS 7.5 integrates and enhances existing extensions while still providing additional extensibility and customization.

  WebDAV and FTP

  WebDAV and FTP functionality available in IIS 7 has been greatly enhanced by incorporating many new features that enable Web authors to publish content more reliably and securely than before. The new FTP and WebDAV modules also offer Web server administrators
more options for authentication, auditing, and logging.

  Request Filtering

  The Request Filtering module, previously available as an extension for IIS 7, helps prevent potentially harmful requests from reaching the server by allowing you to restrict or block specific HTTP requests.

  Administration Pack modules

  Extension modules previously available for IIS 7 as part of the IIS Administration Pack offer additional tools to help you administer your IIS 7.5 Web server from IIS 管理器. These modules include the Configuration Editor and UI extensions that will help
you manage Request Filtering rules, FastCGI, and ASP.NET application settings.

  Management enhancements

  IIS 7.5 has the same distributed and delegated management architecture as IIS 7, but IIS 7.5 also offers new administration tools.

  Best Practices Analyzer

  Best Practices Analyzer (BPA) is a management tool that can be accessed by using Server Manager and Windows PowerShell. BPA can help administrators reduce best practice violations by scanning an IIS 7.5 Web server and reporting when potential configuration
issues are found.

  Windows PowerShell Provider and cmdlets

  The IIS module for Windows PowerShell is a Windows PowerShell snap-in that allows you to perform IIS administrative tasks and manage IIS configuration and run-time data. In addition, a collection of task-oriented cmdlets provide a simple way to manage
Web sites, Web applications, and Web servers.

  Configuration logging and tracing

  Configuration logging and tracing allows you to audit access to the IIS configuration and to track successful or failed modifications by enabling any new logs that become available in the Event Viewer.

  Application hosting enhancements

  Offering a variety of new features that help increase security and improve diagnostics, IIS 7.5 is an even more flexible and manageable platform for many types of Web applications, such as ASP.NET and PHP.

  Service hardening

  Building on the IIS 7 application pool isolation model that increased security and reliability, every IIS 7.5 application pool now runs each process as a unique, less-privileged identity.

  Managed service accounts

  Domain accounts that have passwords managed by the host computer are now supported as service identities in IIS 7.5. This means that server administrators no longer have to worry about expiring application pool passwords.

  Hostable Web Core

  Core IIS Web engine components can be consumed or hosted by other applications. This lets IIS components service HTTP requests directly in an application. This is useful for enabling basic Web server capabilities for custom applications or for debugging
applications.

  Failed Request Tracing for FastCGI

  In IIS 7.5, PHP developers that use the FastCGI module can implement IIS trace calls within their applications. Developers can then troubleshoot application errors by using IIS Failed Request Tracing to debug the code during development.

  Enhancement to .NET support on Server Core

  The Server Core installation option of Windows Server 2008 R2 provides support for the .NET Framework 2.0, 3.0, 3.5.1, and 4.0. This means you can host ASP.NET applications, perform remote management tasks from IIS 管理器, and locally run cmdlets included
with the Windows PowerShell Provider for IIS.

  Who will be interested in these features?

  Any business or organization that hosts or develops Web sites or Windows Communication Foundation (WCF) services can benefit from the improvements made in IIS 7.5.

  The following groups might be interested in these changes:

  Enterprise IT planners and designers for organizations.

  IT professionals who deploy or administer IIS.

  Developers who create Web sites or WCF services.

  Internet service providers (ISPs) or similar organizations that provide Web hosting.

  Which editions include the Web Server (IIS) role?

  This feature is available in all editions.
