Remarks

The ApplicationName property is used by the SqlPersonalizationProvider class to group user information. By qualifying user information with an application name, you can store information for multiple applications in a single database without running into conflicts between duplicate user names. Also, multiple ASP.NET applications can use the same user database by specifying the same value in the ApplicationName property. The ApplicationName property can be set programmatically, or it can be set declaratively in the configuration file for the Web application using the applicationName attribute in the <providers> section.

If a value is not specified for the applicationName attribute in the configuration file for the Web application, then the ApplicationVirtualPath property value for the first request made to the application is used.

Caution

Because a single default personalization provider instance is used for all the requests served by an HttpApplication object, you can have multiple requests executing concurrently and attempting to set the ApplicationName property value. The ApplicationName property is not thread-safe for multiple writes, and changing the ApplicationName property value can result in unexpected behavior for multiple users of an application. It is recommended that you avoid code to allow users to set the ApplicationName property unless required. An example of an application where setting the ApplicationName property might be required is an administrative application that manages personalization data for multiple applications. Such an application should be a single-user application and not a Web application.
