Tomcat 5.5 Cluster: Session Replication before sending the response

Hi everybody, I have a Tomcat 5.5 cluster with 2 nodes on SLES8 and want to replicate the complete session before the response is send. According to the Tomcat Clustering documentation the example with the DeltaManager does this since the ReplicationValve triggers the replication after the requ

Hi Filip, Thanks for your answer. I also thought about this solution of just setting all objects again at the end of the doGet method. But if possible I would like to use a tomcat replication mechanism since I do not want to "manage" session since I have a tomcat-built-in session manager :) And

Hi Rainer, Thanks for your help. To me it sounds like Filip's solution using a servlet filter or another valve and set all session attributes again in combination with the deltaManager is the best solution at the moment looking at the cost-value ratio. Regards, ---Andy -Ursprüngliche Nac
