How to share sessions

How do I share sessions? I want to get the session on another Resin, so how can I get it?

In Resin 4.0, you can enable distributed sessions with the use-persistent-store tag in the session-config. Resin will automatically keep the servers current with the latest session values. The resin-web.xml configuration looks like the following:

WEB-INF/resin-web.xml

<web-app xmlns="http://caucho.com/ns/resin">

   <session-config use-persistent-store="true"/>

 </web-app>
