Round Robin two pools

Something like this should do the trick...

when RULE_INIT {
  set ::NEXT_POOL 0  
}
when CLIENT_ACCEPTED {
  if { $::NEXT_POOL == 0 } {
    pool pool_a
    set ::NEXT_POOL 1
  } else {
    pool pool_b
    set ::NEXT_POOL 0
  }
}

This creates a global variable "NEXT_POOL" and then on each connection it toggles the pool to use.

I don't know how to get away without making use of a global variable.
