Get RST, want closing handshake

Here's a related snippet I found:

rule test_tcp_close_rule {
   when CLIENT_ACCEPTED { 
      TCP::collect
   } 
   when CLIENT_DATA { 
      TCP::respond [TCP::payload]
      TCP::release
      TCP::close
   }
}
If you associate a pool with vip, bigip will send out the FIN to
close connection; but if there is no pool assoicated, bigip will
send reset to close the conneciton. In either situation, bigip
will send the response back to client.

I couldn't find any CR's that related to this description though...
