If multiple users are editing the same page in real-time in a [cluster setup|https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Clustering/DistributedEventClusterSetup/] they may end up in different real-time sessions depending on the cluster node they are served by. Basically each cluster node will have its own real-time session. We need to synchronize the real-time session between cluster nodes or make sure that all users are calling the same WebSocker WebSocket end-point (from one of the cluster nodes). |
