ASP.NET in a Nutshell

Name

<location>

Synopsis

<location
   path=pathToConfigure
   allowOverride=boolean >
   <system.web>
      <! --  Configuration settings  -- >
   </system.web>
</location>

Allows you to prevent settings in machine.config or web.config from being overridden in child configuration files. You can also use it to configure settings for specific files or folders from a configuration file in a parent folder.

Scope

Any

Attributes

path

Specifies the path to the file or folder to which the configuration settings contained in the <location> tag pair should be applied.

allowOverride

Specifies whether child configuration files can override values configured within the <location> tag pair. This attribute locks down configuration settings (i.e., at the machine.config level) for which you want to enforce uniformity.

Child Elements

<system.web>

Example

The example, if used in machine.config, would force all applications on the machine to use Windows authentication:

<configuration>
   <location
      allowOverride="false">
      <system.web>
         <authentication mode="Windows">
      </system.web>
   </location>
   <system.web>
      <!-- Other configuration settings -->
   </system.web>
</configuration>

Notes

This tag provides powerful control over configuration. In addition to the scenario of enforcing an authentication method across all applications, you can also use the path attribute to configure multiple child folders or files from the web.config file in the root of the application. Using this configuration can avoid having a large number of child web.config ...
