Sun Java System Portal Server 7.1 Deployment Planning Guide

Multiple Gateway Instances

If desired, you can run multiple Gateway instances on a single machine. Each Gateway instance listens on separate ports. You can configure Gateway instances to contact the same Portal Server instance, or different Portal Server instances. When running multiple instances of a Gateway on the same machine, you can associate an independent certificate database with each instance of the Gateway, and bind that Gateway to a domain. This provides the flexibility of having a different Gateway server certificate for each domain.
