when HTTP_RESPONSE {
  if { [HTTP::cookie exists "JSESSIONID"] } {
    set jsessID [lindex [split  [HTTP::cookie "JSESSIONID"] "!" ] 0 ]
    if { [session lookup uie $jsessID] equals "" } {
      session add uie $jsessID [IP::server_addr] 1800
     log local0. "added server entry [session lookup uie $jsessID] for jsessionID $jsessID "
    } else {
       log local0. "existing server entry [session lookup uie $jsessID] for jsessionID $jsessID"

    pool myApp-pool member [session lookup uie [findstr [HTTP::uri] "jsessionid" 11 "!"] ]
   log local0. "jsessionID [findstr [HTTP::uri] "jsessionid" 11 "!"] sent to [session lookup uie [findstr [HTTP::uri] "jsessionid" 11 "!"] ]"
  } else {
      pool myApp-pool
     log local0. "No jsession ID, local balancing the connection..."
  }
}
