Summary of configuration information for the Web.config of application

The Web.config file is an XML text file used to store configuration information for the ASP.NET Web application (such as the most commonly used Settings for the authentication of the ASP.NET Web application), which can appear in each directory of the application. When you create a new Web application via.NET, a default Web.config file is automatically created in the root directory by default, including the default configuration Settings, which all subdirectories inherit. If you want to change the configuration Settings of the subdirectory, you can create a new Web.config file in the subdirectory. It can provide configuration information in addition to configuration information inherited from the parent directory, or it can override or modify Settings defined in the parent directory.

Changes to the Web.config file take effect at run time without restarting the service (note: section exception). Of course the Web.config file is extensible. You can customize new configuration parameters and write configuration section handlers to handle them.
