An IP sprayer has many names:
1) IP sprayer
2) network sprayer
3) load balancer
4) network dispatcher
5) load dispatcher
6) and even cache server is used sometimes
But the functionality is the same. You want to spread the load on different servers, or maybe have failover servers.
Is there a freeware dispatcher out there?.
I intend to use it in front of a Lotus Domino cluster. Yes I know about the websphere Edge Components, but it costs a fortune. The Domino cluster solution with ICM alone is not optimal. The problem is that ICM produces different URLs when it routes a request to a server in the cluster.
The Lotus Domino administrator give us the idea that an IP sprayer should be used instead of the ICM. Again, is there a free IP sprayer out there?
