How to add multiple custom headers

Hi,

I'm trying to modify the properties(HTTP Headers) of a virtual directory. I need to to do two tasks:

1. Enable content expiration
2. Add custom http headers (key: value)

Here is my approach:

.....
set objIISRoot = CoGetObject("IIS://Localhost/W3svc/1/Root/testVD", "");
if IsObject( objIISRoot ) then

objIISRoot.HttpExpires = "D, 0";
objIISRoot.HttpCustomHeaders ="key: value";

objIISRoot.SetInfo();
....

But the problem is: I can not assign multiple customHeaders.

How can i assign MULTIPLE CUSTOM HEADERS? it does not accept any array type or list type? what should i do?
