Distributed Sessions check_circle

For authenticated users, the Jahia stores data in the HTTP session. By default, this data is stored in the memory of the server, where requests of a session are routed to. When the server is shut down, all this session data disappears and the user will have to login again and eventually re-do steps. For higher availability and up-time we recommend replicating the session data on all servers, so that sessions survive a stopped server and that other servers can continue working on user requests, which were previously served from the stopped server. 

Starting with v2.0.0, the distributed-sessions module offers the ability to distribute sessions on all servers with hazelcast.

The Jahia Academy contains dedicated documentation detailing distributed session usage for Jahia 8 and for Jahia 7. Please make sure to review this document prior to deploying the distributed-session module.

Note about version 3.4.0

Distributed Sessions 3.4.0 does not depend to jahia-csrf-guard 3.2.0 anymore. So you may need to upgrade also jahia-csrf-guard. Both modules updates will require the restart of the cluster nodes. More details here.

Improvements

  • Removed dependency to jahia-csrf-guard
