Convert Citrix Netscaler rule to F5 Persistence Profile or iRule

Our agency has an industry specific application that uses an executable shell to launch IE and connect to a back end server for the http traffic. Our problem is that persistence isn't working correct...

I'm not sure I have the nuances of the Citrix rule down pat, but I suspect this is what you need with a Universal persistence profile (see http://support.f5.com/kb/en-us/solutions/public/7000/300/sol7392.html);-

when HTTP_RESPONSE {
    if { [HTTP::cookie exists "GreenwaySession"] } {
        persist add uie [HTTP::cookie "GreenwaySession"]
    }
}
when HTTP_REQUEST {
    if { [HTTP::cookie exists "GreenwaySession"] } {
        persist uie [HTTP::cookie "GreenwaySession"]
    }
}

After extensive testing the universal persistence profile isn't working. It appears that it should, but testing revealed persistence was not a good as using a simple http cookie rule. At this point I think abandoning the F5 for load balancing for this application is the only option.
