How would I write a Set-Cookie header for $cookie_name, $cookie_value,
$expiry,  $specified_domain?

To restate the problem: I am handing off data from my site to a secure
credit-card processing site (which is in a frameset).  Once the transaction
has been confirmed I want to load a page from my site into a frame of the
third-party site to read the cookie.

My current work-around is to load an interstitial page into that frame,
which launches a separate window which reads the cookie.  However because
of concerns about "anti-pop-up" software as well as limited user system
resources i would prefer not to use this method.  The ability to read this
cookie is "mission critical".
