wlnode function

I am trying to use a similar rule to persist to weblogic servers based on the jsession id; here is my rule

when HTTP_RESPONSE {
       set key [HTTP::cookie "JSESSIONID"]
       set value [IP::server_addr]:[TCP::server_port]
       if {$key != ""} {
          log local0. "Adding jsess of: $key, value of: $value"
          session add uie $key $value
          set value2 [session lookup uie $key]
          log local0. "Re-looking up key: $key, provides value: $value2"
       }
     }
     when HTTP_REQUEST {
       set jsess [findstr [HTTP::uri] "jsessionid" 11 ;]
       log local0. "Entering REQUEST, jsess is: $jsess"
       if { $jsess != "" } {
          set server [session lookup uie $jsess]
          log local0. "Server IP is: $server"
          if { $server != "" } {
             pool pool_weblogic_pool_http member $server
          }
       }
     }

I am having an issue where I am consistenly presented with a "We're sorry but your session has timed out" error presented by the app/web server

here is what my ltm log says
