My problem is that my application renders HTML content integrated inside 
  iframes on another site maintained by our client (yes I know, frames 
suck, but that's how it was specified). The application offers various 
services that are invoked by the parent site at www.mydomain.com/service

The problem are:
  - www.mydomain.com doesn't always point to the same server (because of 
round-robin DNS)
  - the various services must communicate (there's a notion of logged in 
user common to all services)

I use a session cookie and other cookies to remember vital information, 
but I can't manage to stick a client to one server once he has started a 
session. That's why I wanted this domain cookie. I want to store the 
name (or IP, or whatever) of the server that initialized the session, to 
redirect the user to the correct server if he tries to open a session on 
another one. But to do this I need a domain-wide cookie.

If someone has an idea on how to integrate a seaside site to another 
site without IFRAMES, I'm open to any suggestions.
