Hello, I have Flex, BlazeDS, Spring, java application working in Standalone Tomcat Instance. For scalability we decided to test in Vertical Cluster of three Tomcat Instances. Initially we tested a simple JSP maintaining session attribute of counter in HAProxy, Memcached-Session-Manager (MSM) and Couchbase-Server for session replication and that test got passed.
Secondly we decided to Test the working Flex application in that cluster. Initially Kryo serialization gave problems so we shifted to java serialization and application could Load. But we started getting error "Detected duplicate HTTP-based FlexSessions, generally due to the remote host disabling session cookies. Session cookies must be enabled to manage the client connection correctly" I googled a lot for Clutering Flex-BlazeDS application howtos but could not succeed. Can somebody help us in this situation. we are using Flex 4.6, BlazeDS 4.0, Spring BDS Integration 1.5.2, Spring 3.1.2, Open JDK 1.6, Tomcat 7.0.29, on Ubuntu 12.04. HAproxy, Couchbase-server installed from repository, MSM downloaded from its site and configured according to wiki page for it. Thanks and warm regards Raja Patil
