FIX: IIS 6.0 Does Not Return AUTH_TYPE for Integrated Security

Article ID: 824330 - View products that this article applies to.

SYMPTOMS

If you use Integrated security to authenticate users on your Web page, and if you want to use the AUTH_TYPE Microsoft Internet Information Services (IIS) server variable in your application, for example from Active Server Pages (ASP) script through Request.ServerVariables("AUTH_TYPE"), AUTH_TYPE may be empty.

CAUSE

For Integrated security, the AUTH_TYPE IIS server variable is populated if the Authorization header is present in the request. Because the Authorization header is only present for the first request, the AUTH_TYPE IIS server variable is not populated for the next requests.
