This is a common problem, and the easiest solution, if you have control over
both domains, is to put a "bug" (a small image) on domain1 and domain2,
something like:
showlogo.php
Which returns a jpeg of an image. The trick is that you send it a parameter
such as:
http://domain2.com/showlogo.php?session=MYSESESSION
Then this code sets its cookie in domain2, so when you go there it is there.
You should try to use encryption, temp variables, or something to keep this
from being easy to hack.
