What is new in IIS 7?
IIS 7.0 Components
IIS7 contains several components that perform important functions for the application and Web server roles in Windows Server® 2008. Each component has responsibilities, such as listening for requests made to the server, managing processes, and reading configuration files. These components include protocol listeners, such as HTTP.sys, and services, such as World Wide Web Publishing Service (WWW service) and Windows Process Activation Service (WAS).
Protocol Listeners
Protocol listeners receive protocol-specific requests, send them to IIS for processing, and then return responses to requestors. For example, when a client browser requests a Web page from the Internet, the HTTP listener, HTTP.sys, picks up the request and sends it to IIS for processing. Once IIS processes the request, HTTP.sys returns a response to the client browser.
By default, IIS7 provides HTTP.sys as the protocol listener that listens for HTTP and HTTPS requests. HTTP.sys was introduced in IIS 6.0 as an HTTP-specific protocol listener for HTTP requests. HTTP.sys remains the HTTP listener in IIS7, but includes support for Secure Sockets Layer (SSL).
To support services and applications that use protocols other than HTTP and HTTPS, you can use technologies such as Windows Communication Foundation (WCF). WCF has listener adapters that provide the functionality of both a protocol listener and a listener adapter. Listener adapters are covered later in this document. For more information about WCF, see Windows Communication Foundation on MSDN.
World Wide Web Publishing Service (WWW service)
In IIS7, functionality that was previously handled by the World Wide Web Publishing Service (WWW Service) alone is now split between two services: WWW Service and a new service, Windows Process Activation Service (WAS). These two services run as LocalSystem in the same Svchost.exe process, and share the same binaries.
HTTP Administration and Configuration
WWW Service reads configuration information from the IIS metabase and uses that information to configure and update the HTTP listener, HTTP.sys. In addition, WWW service starts, stops monitors, and manages worker processes that process HTTP requests.
Performance Monitoring
WWW Service monitors performance and provides performance counters for Web sites and for the IIS cache.
IIS 7.0 Modules
IIS7 provides a new architecture that is different from previous versions of IIS. Instead of keeping the majority of functionality within the server itself, IIS7 includes a Web server engine in which you can add or remove components, called modules, depending on your needs.
Modules are individual features that the server uses to process requests. For example, IIS uses authentication modules to authenticate client credentials, and cache modules to manage cache activity.
The new architecture provides the following advantages over previous versions of IIS:
You can control which modules you want on the server.
You can customize a server to a specific role in your environment.
You can use custom modules to replace existing modules or introduce new features.
The IIS7 architecture also improves security and eases administration. By removing unnecessary modules, you reduce the server’s attack surface and memory footprint, which is the amount of memory that server worker processes use on the machine. You also eliminate the need to manage features that are unnecessary for your sites and applications.
