One question Jay...
Is there any way that two users can hit two different servers (in a
clustered environment) and each server creates the same cfid/cftoken
combination?

Subject: Re: Session vars in a clustered environment
Howard,
I've never used session vars in a clustered server setup, but I've read a
lot about doing it, so here goes nothing :-)

You can setup the clustering server to use Sticky Sessions - though, this
isn't a truely load balanced solution. Using load balancing, the idea is
that the load will be distributed over all the servers in the cluster. With
sticky sessions, that happens only to a certain extent - once a user is
assigned to a server, the user stays on the server, regardless of the load
so that the session vars are preserved.

If you're using Sticky Sessions, it should be fine.

Configure CF server to store client variables in a database - storing client
vars in the registry is a bad idea in any setup beacuse if the registry hits
its max size, all sorts of undesireable things will happen :-(. In a
clustered setup, if you setup CF to store the cient vars in the db, they
should be accessble to all the servers in the cluster.
