The login context is the conversational state. The session cookie is the
long term state. Two different things.

I don't know if the database option even stores transient mappings in the
first place. If so, yes, but it has nothing to do with "different nodes".
The client stick has nothing to do with which server an SP will talk to.

If you take a node down, no matter what solution is used except for
Terracotta, anybody in the middle of the request/response sequence or
sitting on the login page will get an error.
