Configuration information for ASP.NET resources is contained in a collection of configuration files each named Web.config. Each configuration file contains a nested hierarchy of XML tags and subtags with attributes that specify the configuration settings. Because the tags must be well-formed XML the tags subtags and attributes are case-sensitive. Tag names and attribute names are camel-cased which means that the first character of a tag name is lowercase and the first letter of any subsequent concatenated words is uppercase. Attribute values are Pascal-case which means that the first character is uppercase and the first letter of any subsequent concatenated words is uppercase. Exceptions are true and false which are always lowercase.
All configuration information resides between the <configuration> and </configuration> root XML tags. Configuration information between the tags is grouped into two main areas: the configuration section handler declaration area and the configuration section settings area.
Configuration section handler declarations appear at the top of the configuration file between <configSections> and </configSections> tags. Each declaration contained in a <section> tag specifies the name of a section that provides a specific set of configuration data and the name of the .NET Framework class that processes configuration data in that section.
The configuration section settings area follows the <configSections> area and contains the actual configuration settings. There is one configuration section for each declaration in the <configSections> area. Each configuration section contains subtags with attributes that contain the settings for that section.
