Attributes and Elements
The following sections describe attributes, child elements, and parent elements for this element.
Attributes
Attribute |
Description |
|---|---|
allowOverride |
Optional Boolean attribute. Specifies whether configuration settings can be overridden by configuration settings that are in Web.config files that are in child directories. The default is True. |
path |
Optional String attribute. Specifies the resource that the contained configuration settings apply to. Using location with a missing path attribute applies the configuration settings to the current directory and all child directories. If location is used with no path attribute and allowOverride is False, configuration settings cannot be altered by Web.config files that are in child directories. |
inheritInChildApplications |
Optional Boolean attribute. Specifies whether configuration settings that are specific to a certain location (such as the root directory of a Web site) are inherited by applications that exist in subdirectories. The default is True. |
Child Elements
The location element can enclose other elements, either to apply configuration settings to a specific resource or to lock the configuration settings.
Parent Elements
