Chikashi, you can redirect users to a specific URL using this REST call:
You would need to write a custom service around it though.
If we use services, I guess we need to know the current session idle time.
I saw the "CurrentSessionInfo" and "UserManagementSubsystem", but could not find way to know the current session idle time.
The default idle timeout is "30", and I think the tomcat monitor it with JSESSION ID cookie.
Is there anyway to know the current session idle time?
