I have the need for Multiple Clusters using only 2 servers. Possib

I was asked by managment to find a solution to a problem. We run a web
application and are moving towards SSL and I was asked to create a "Multiple
Cluster Web Server environment. the reason being to battle a SSL and non-host
header issue.

I currently run a NLB cluster with Multiple External IP's that point to the
NLB IP address. This works fine. Right now I have two window 2k3 server-Web
edition serves, dual nic's, 3 external IP addresses, 3 sites needing to use
SSL/non-host headers. I need to create 3 seperate clusters for each site and
associate a different external address to the cluster.

is this possible to do with the amount of servers I have and the OS version
I am using?

if not, can someone recommend a product or a solution

thanks
