                                            args As AnonymousIdentificationEventArgs)
  args.AnonymousID = Samples.AspNet.Security.MyIdClass.GetAnonymousId()
  Samples.AspNet.Security.MyIdClass.LogAnonymousId(args.AnonymousId)
End Sub

Remarks

The AnonymousIdentificationEventHandler delegate is defined for the Creating event of the AnonymousIdentificationModule class. You can access the Creating event of the AnonymousIdentificationModule class by specifying a subroutine named AnonymousIdentification_Creating in the Global.asax file for your ASP.NET application. The Creating event is raised during the PostAuthenticateRequest event.

The AnonymousIdentificationModule constructs an AnonymousIdentificationEventArgs object using the current HttpContext and passes it to the AnonymousIdentification_Creating event.

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 anonymous identification is Enabled by setting the <anonymousIdentification> configuration element to true.
