Cookies In Global.asa

Set IE 6.0 ver. X to "Block all Cookies" in privacy settings and try
this code in three separate files.

<-- Global.asa -->
sub Session_OnStart
response.cookies("test") = "-1"
end sub
<-- Global.asa -->

<-- testcookie1.asp -->
<%Response.Redirect("testcookie2.asp")%>
<-- testcookie1.asp -->

<-- testcookie2.asp -->
<%=request.cookies("test")%>
<-- testcookie2.asp -->

I get "-1" on testcookie2.asp

Anyone else get the same result?
Why am I getting the cookie in this test?
