Not persisted objects as user sessions are better indicators to test if the cache is replicating.</SPAN><BR /><BR /><SPAN>Regards </SPAN><BR /><SPAN>JSP</SPAN></BODY></HTML> Fri, 16 Nov 2012 19:30:48 GMT https://connect.hyland.com/t5/alfresco-archive/ehcache-replication-using-jgroups-over-tcp/m-p/271129#M224259 jspuchau 2012-11-16T19:30:48Z
