CLUSTERS

Compatibility with previous releases of Domino
The ICM directs HTTP client requests to any IBM® Lotus® Domino™ Web server in a cluster. Therefore, using the ICM in a mixed cluster has no negative effect on clients. Only Lotus Domino Release 5 and later Web servers, however, generate URLs that include references to the ICM. When a user selects URLs that contain these references, the ICM is able to balance the workload and redirect the user to an appropriate server.

If the ICM redirects the client request to a server running a previous release of Domino, the URLs that server generates do not contain references to the ICM. As the client moves between Web pages, the client continues to access pages on that server only. To take advantage of the ICM at that point, the user must select or enter a URL that contains a reference to the ICM.
