The Gateway Caching Server is supported in a load-balanced environment. If you configure load balancing, ensure all load-balanced Gateway Caching Servers point to the same network cache location. There should be only one cache per geographic gateway location.
Each Gateway Caching Server must be installed on a separate machine. Load balancing with multiple gateways on the same machine is not supported.
For more information on load balancing, see the Application Server module reference guide.
