I have a Java application running on server A where it is desired to force all users to go thru a survey on server B before they continue to their desired place on server A. Both servers are using the same version of the JVM; two tomcats (same version) are utilized. What I am seeing is that a user can log in and be authenticated on server A and then be redirected to server B and complete the survey with no problems. However, when I try to go back from server B to server A, I cannot seem to join the correct user session! What do I need to be doing to join the correct session?
