Get current default pool name in an iRule?

Is it possible to query the current value of the default pool on a virtual server in an iRule so that it can be compared to the connection's [LB::server pool] value?   Thanks.   EDIT Thanks for...

You can query the default pool name before the LB decision is made:

when CLIENT_ACCEPTED {
   Save the name of the VIP's default pool
  set default_pool [LB::server pool]
}
LB::server pool

Returns the pool of the currently selected member. If no server was selected yet or all servers are down, returns default pool name.
