redirect to pool member based on Subnet

I am very new to iRule creation. I have a group of subnets that need to be directed to a specific pool member when any traffic from them comes into the VIP.     Any help is appreciated!   ...

vs variable and SERVER_CONNECTED event are used for logging. please feel free to remove it.

this is data group version. 

[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when CLIENT_ACCEPTED {
        set vs "[IP::local_addr]:[TCP::local_port]"

        if {[class match -- [IP::client_addr] equals subnet_list]}{
                pool foo1
        } else {
                pool foo2
        }
}

when SERVER_CONNECTED {
        log local0. "[IP::client_addr]:[TCP::client_port] -> $vs -> [IP::server_addr]:[TCP::server_port]"
}
}
[root@ve1023:Active] config  b class subnet_list list
class subnet_list {
   network 172.28.19.0/24
}

[root@ve1023:Active] config  cat /var/log/ltm
