Hazelcast IMDG Standard Support has expired. Extended support for version 4.1 ends in April 2024. Extended support for version 4.2 ends in September 2024.

We recommend that you try Hazelcast Platform.

In Hazelcast Platform, we’ve combined the in-memory storage of IMDG with the stream processing power of Jet. Find out more in our Platform documentation.

The following topics are a good place to start:

Web Session Replication Plugins

You can use Hazelcast to replicate your web session in a number of environments.

Filter Based Web Session Replication

This plugin (a.k.a. Generic Web Session Replication) provides HTTP session replication capabilities across a Hazelcast cluster in order to handle failover cases. Assuming you have multiple web servers with load balancers; if one server goes down, your users on that server are directed to one of the other live servers, but their sessions are not lost. Using this plugin backs up these HTTP sessions; it clusters them automatically.

Tomcat Based Web Session Replication

Tomcat based web session replication is offered through Hazelcast Tomcat Session Manager. It is a container specific module that enables session replication for JEE Web Applications without requiring changes to the application.

See the following for more details:

Jetty Based Web Session Replication

Jetty based web session replication is offered through Hazelcast Jetty Session Manager. It is a container specific module that enables session replication for JEE Web Applications without requiring changes to the application.

See the Jetty: Persistent Sessions with Hazelcast for more details.
