Has anybody used any load-balancer application with unigui ?
As Farshad Mohajeri says
Load balancing is another issue. uniGUI apps can be load balanced. To achieve this a specialized load-balancer application is needed. Load balance app will recognize uniGUI web requests and after extracting the session info, request will be redirected to server which is keeping the state for that session. Each request should be redirected to the server which has initiated that particular session. Requests can not wander around different servers as it is possible in a stateless server farm. All these may make load-balancing a bit more complex, but it is achievable.
