How to reset AnonymousID in ASP.NET MVC?

Question

On some reasons some users get null AnonymousID on my site. I want to reset them to new Guids , but how?

Trying to do this:

public void AnonymousIdentification_Creating(object sender, 
   AnonymousIdentificationEventArgs args)
{ 
    args.AnonymousID = Guid.NewGuid().ToString();
}

And this:

protected void Application_EndRequest(object sender, EventArgs e)
{
   if (Request.IsAuthenticated && Request.AnonymousID == null)
   {
   System.Web.Security. 
       AnonymousIdentificationModule.ClearAnonymousIdentifier();
   }
}

AnonymousID reset to null, but not assing new. And no AnonymousIdentification_Creating invokes.

It there any way manually set or reset to new AnonymousID ?

UPDATED: <anonymousIdentification enabled="true" /> also.

By default Anonymous Identification is disabled in MVC. To enable this, you need to add the following tag in web.config under configuration => system.web tag:

<anonymousIdentification enabled="true" />
