The web.config configuration file for IIS 7.0 is a little different compared to the web.config file used for IIS 6.0.
The main difference is that the system.web section is no longer used, but instead the configuration settings are read from the system.webServer section.

However, that change only applies to IIS specific settings, such as the configuration of (Http) Handler Mappings and (Http) Modules. Configuration settings for ASP.NET, such as membership and rolemanager providers, will still use the system.web section.

The articles in this section concentrate on the system.webServer section, since the other sections are no different and are already covered within the web.config for IIS 6.0 articles.
