Passing header variables to another page

I'm trying to pass a header variable "SMUSERDN" with a value of "reportingonly" to this page - https://qaanz13.corp.ad.local/cv/logproc.asp.

The page I'm redirecting from looks like this:

<%@ LANGUAGE="VBSCRIPT" %>
<%
Option Explicit
On Error Resume Next
%>

<%
Response.AddHeader "SMUSERDN","reportingonly"

Response.Redirect "https://qaanz13.corp.ad.local/cv/logproc.asp"
%>

I can't get this to work. 
The request doesn't seem to have that header variable in it.
Any ideas on what I am doing wrong?
