If you use round-robin DNS, it is unlikely that the user will be sent to one server, then another. When the user attempts to connect initially, the DNS server will issue one IP address, and that IP address will be cached for some time by the client. Even if that first server fails, the user will not be sent to another server. Aside from that, though, I don't think there's any way to share CFLOGIN data without associating it with the Session scope, and sharing that across the servers. This would require CF clustering. When you use the CFLOGIN tag, it does write a cookie which contains something, but I don't know if it contains everything that is set by CFLOGINUSER.
