Hi Aaron: Thanks for the reply. I tried sniffing the traffic and looked for any string that I can use to identify the client but there are none. This application unfortunately doesn't use ASP sessions, all its sessions are within the app itself within the payload. I was thinking how a custom cookie insert would work but if the requests are all coming from the same server(Citrix), I am not sure how the client side identity will be unique, which might again force the traffic to go to only one node.
I made a couple of request using the app and took a tcpdump(attached, rename to dmp). Couldn't find any layer7 stuff that I could use.
