Similar feature to LB::status under v9.0.5

Hi,     We are about to use iRules to load balance servers based on the state of other servers. For example the rule would look like "if poolB-node3 down go node poolA-node1 else use poolA".  ...

You could still pick the specific pool member and if it turns out to be down, the LB_FAILED event would be triggered and you could reselect another pool member or repick the pool to have it load-balance to any other available pool member. The LB::server command is available in 9.0.5 and it will return the currently selected pool/member so you can test which pool member is down. You may also want to use a variable to additionally control the behavior in the LB_FAILED event since it may be triggered multiple times in the event additional pool members are down.
