Hi RP,

You should be able to implement this logic by applying two monitors with the destination port configured. Here's an example which creates a dependency on port 80 and port 8080 for each pool member: 


monitor http_8080 {
   defaults from http
   dest *:8080
   recv "200 OK"
   send "GET / HTTP/1.1\r\nHost: \r\nConnection: Close\r\n\r\n"
}
monitor http_80 {
   defaults from http
   dest *:80
   recv "200 OK"
   send "GET / HTTP/1.1\r\nHost: \r\nConnection: Close\r\n\r\n"
}

You could then set the pool's service on action down to reselect.
