Got it. How about this:
- every login form sets a session ID
- immediately after logging in the user is directed to a page showing that
successful login has occurred. The result screen could could have some
images (or whatever) such as this:
<img src="http://www.otherdomain.com/img/auth.gif?session=2345r8hrfd";>
- above example of gif would actually be a script that returns a tiny
(invisible) gif which verifies that the session is valid and sends a cookie
for the new domain if it is. There would be one such embedded image for
each extra domain.
I've been out of web development for a while so it took me a bit to get my
head around this requirement. Does my explanation make sense and seem
feasible?
Thanks
