How do I setup sticky connections for Citrix Web Interface using CSS in a Secure Gateway environment?

Thanks for the comments. Our SSL side via SG is functioning. In CSS this is fairly easy. The load balancing method is SSL. If it's not SSL you have a wide range of options.

Application Type is: HTTP
Advanced Balance Method: SSL, cookieURL, URL, cookies, sticky-srcip-dstport, sticky-srcip, arrowpoint cookie.

I've tried all of the those options to maintain a connection to the same server, but it appears to not function. The closest I've come is using the Advanced Balance Method "cookies" with a string operation of match-service-cookie. In addition I've assigned a string to each WI server service. This will function for awhile using the WI, but it will fail and send me to the logged off screen when I attempt to navigate within the WI if I wait for a 30 seconds or so. When it does send me to the logged out screen the address bar will read ..MessageKey=SessionExpired.. Then it will be broken until I delete my cookie that is provided from the WI. Do I need to change my keepalive type (default is icmp)? It almost seems like a time-out issue of some sort.
