Sticky Sessions and Load Balancing

We are hosting an application on multiple Windows Server 2008 and IIS7.5 with an F5 load balancer. Our application is not functioning when multiple servers are in the cluster bu operates correctly when only one server is in the cluster. Does Mendix required server affinity/sticky sessions in order to run in a load balanced environment? Persistent sessions are enabled.
