ASP.NET has several configuration section handlers for defining configuration settings within the <system.web> section of Web.config files.
The following sections describe each of the configuration sections in detail and show the full syntax that each supports.
The tags listed below and their subtags and attributes must be well-formed XML and are case-sensitive. Note that for configuration tags and attribute names, the first character is lowercase and the first character of subsequent concatenated words, if any, is uppercase. For attribute values that are members of an enumeration, the first character is uppercase and the first character of subsequent concatenated words, if any, is uppercase. Exceptions are true and false, which are always lowercase.
