Occurs when a new anonymous identifier is created.
Assembly: System.Web (in System.Web.dll)
The event is raised during the PostAuthenticateRequest event.
You can access the event of the AnonymousIdentificationModule class by specifying a subroutine named AnonymousIdentification_Creating in the Global.asax file for your ASP.NET application.
You can use the AnonymousId property of the AnonymousIdentificationEventArgs object supplied to the AnonymousIdentification_Creating event to set the anonymous identifier to a custom value. If you do not specify a value for the AnonymousId property during the AnonymousIdentification_Creating event, a Guid is used.
The AnonymousIdentification_Creating event is only raised when the anonymous identification is Enabled.
The following code example uses the AnonymousIdentification_Creating event to set the anonymous identifier to a custom value.
