Enable session on anonymous pages

Enable public sessions for portal. The reason is that the theme/portlet needs a valid session for its run time, and by default, sessions are not enabled on anonymous pages in the portal. By default, sessions are only created when a user authenticates and logs in to the portal.

Enable public sessions by setting the parameter public.session to true (String type) in the portal "WP NavigatorService > Custom properties > New" in the WebSphere Integrated Solutions Console.
