how to ensure that 'client' requests which orginate from a load-balanced server are sent to itself by the load balancer

Hi Rob -

Here's a rule that will:

1) send "normal" traffic to the pool

2) sends "bounceback requests" (from real server to virtual server) to itself if it is UP

3) sends bounceback requests to the pool if the requested server is not UP.

when CLIENT_ACCEPTED {
  if { [matchclass [IP::remote_addr] equals $::serverIPs] }{
    if { [LB::status pool myPool member [IP::remote_addr] 23] ne "down"}{
      pool myPool member [IP::remote_addr] 23
    } 
  } else {
      pool myPool
  }
}

(substitute the real pool name and the correct port if it is not 23).

Create a class (data group list) of IP addresses called serverIPs which contains the IP addressed of the servers in the pool, and apply the iRule to the virtual server.
