Script to distinguish between Certificate Authorities (ex. Verisign, Thawte) SSL

Hi,

I'm wondering if anyone can help me out with a problem I'm facing.

I need to have conditional code on a web page (asp) to show who the site
authenticating Certificate Authority is. Of course the site is set up to
use SSL.

I've examined all IIS Server Variables (Request.ServerVariables).
Unfortunately I was informed that the server variables names with a "CERT_"
prefix are unreliable to test for CA's.

Can anyone help?

One application of this test would be to conditionally put a Verisign or
Thawte logo on a sites log in page.

Thanks.
