The AnonymousIdentificationEventArgs class is used to supply event values to the Creating event and to enable you to specify a custom Windows identity for the current request. 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 AnonymousIdentificationModule constructs a 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 the anonymous identification is Enabled.

The following code example uses the AnonymousIdentification_Creating event to set the anonymous identifier to a custom value.

public void AnonymousIdentification_Creating(object sender, 
                                             AnonymousIdentificationEventArgs args)
{
  args.AnonymousID = Samples.AspNet.Security.MyIdClass.GetAnonymousId();
  Samples.AspNet.Security.MyIdClass.LogAnonymousId(args.AnonymousID);
}
