Yes, it's possible for the servers to share cookies with inter-server
communication. Your server can't ask the client for a cookie that my server
placed on the client, but your server can ask my server what cookie my
server placed on the client. See the distinction? So cooperating servers
can share information from cookies. It's tricky, but it works.
