I'm trying to have a separate server which sends data to the server which serves the web pages and want to do some ajax stuff to do it, but it doesn't seem to be possible either to do xmlhttp stuff across multiple domains or things like framed functions calling their opener if the opener is on a different domain.
Two questions therefore:
1. Is anything like this possible across domains?
2. Is it possible on subdomains such as server1.domain.com and server2.domain.com
