I'm having trouble with my code when I try to connect to a server that asks for a client certificate. If I use the XMLDOM like this...

Dim HttpReq As New ServerXMLHTTP40
HttpReq.open "GET", "I enter my URL here", False
HttpReq.send

What happens is, is a pop-up box pops up asking me to select a certificate from my local store. I can click ok or cancel and either way it will proceed with my request. I'm trying to get it where this pop-up doesn't occur. I tried inserting this additional command...

HttpReq.setOption 3, ""

but this doesn't stop anyting from happening either.

Can anyone suggest a way I can get this thing to stop asking me to pick a client certificate?
