| <p> |
| The Lateral JGroups Auxiliary Cache is an optional plug in for |
| JCS. It is primarily intended to broadcast puts and removals to |
| other local caches, though it can also get cached objects. It uses JGroups |
| for distribution. |
| </p> |
| <p> |
| The Lateral Lateral JGroups Auxiliary Cache is far slower than |
| that Lateral TCP Auxiliary Cache. Since the Lateral TCP Auxiliary |
| is faster and has UDP discovery built in, the TCP auxiliary is the recommended form of lateral |
| distribution. However, the JGroups Auxiliary requires fewer socket connections than |
| the TCP lateral. |

| A functional configuration example is below: |
