Thnx Insite. I think I might have a solution. Since i am using Elastic Load Balancer (ELB) I am going to use sticky sessions. This means (I think) that the same user will be sent back to the same server for a period i set (I plan on using 8 hours). So as long as I replace "localhost" with "researchStudyOnline", I should be good for 8 hours. After that things can go haywire. But I have an inactivity timer set to 120 seconds, so it will be rare for someone to stay on for 8 hours and not take a break. Once they log off and log back on, all is AOK again for another 8 hours.
