Sun Java System Application Server 9.1 Update 1-9.1 Update 2 Release Notes

Highly available webapps deployed at “/” unable to resume in-memory replicated HTTP sessions (Issue Tracker 2972)

Description

Highly available web applications deployed at “/” are unable to maintain any HTTP sessions when using in-memory replication as their persistence type.

Solution

Deploy highly available web applications that use in-memory replication as their persistence type to a context root other than “/”. If you want to make such a web application available at “/”, you may designate it as the default-web-module of the virtual server to which the web application has been deployed.
