FIX: The contents of the Request.ClientCertificate("Certificate") field are incorrect when an .asp Web page is hosted on IIS 6.0 (916833)


The information in this article applies to:

  • Microsoft Internet Information Services version 6.0

SYMPTOMS

Consider the following scenario. You browse an .asp Web page that is hosted on Microsoft Internet Information Services (IIS) 5.0. You then use the same client and keyset to browse the same .asp Web page, but the Web page is hosted on IIS 6.0.

In this scenario, the contents of the Request.ClientCertificate("Certificate") field are incorrect when the page is hosted on IIS 6.0. For example, the last byte of the content is incorrect when you use a COM component to write the content to a certificate in ASN.1 format.

CAUSE

This issue occurs because the size and offset of the certificate content are not calculated correctly when the .asp Web page is hosted on IIS 6.0.
