IIS(Internet Information Services 7.0) HTTP SERVER:

Internet Information Services (IIS) 7 introduces a new XML-based configuration system for

storing your IIS settings that replaces the metabase that was used in IIS 6.0 and earlier. This new

configuration system was introduced with ASP.NET and is based on a hierarchical system of

management system that uses *.config files. The configuration files for IIS 7 are located in your

%WinDir%\System32\Inetsrv\Config folder, and the primary configuration files are:

ApplicationHost.config - This configuration file stores the settings for all your Web sites

and applications.

Administration.config - This configuration file stores the settings for IIS management.

These settings include the list of management modules that are installed for the IIS

Manager tool, as well as configuration settings that any management module uses.

Redirection.config - IIS 7 supports the management of several IIS servers from a single,

centralized configuration file. This configuration file contains the settings that indicate the

location where the centralized configuration files are stored.

Note: Some settings can be delegated to Web.config files, which may override settings in the

ApplicationHost.config file. In addition, settings that are not delegated cannot be added to

Web.config files.
