What port is your VIP defined on? Does your VIP have a client and/or server SSL profile? Is the client making an HTTPS request? Is the server expecting SSL or non-SSL traffic?
If the client makes a request to the VIP on a port other than port 80, the traffic should be sent to the test_pool using your last rule.
Is this failing? If so, what is happening? If you run tcpdump on interface 0.0 filtering on the client or pool members' IP addresses, do you see packets going to/from the pool members?
You can use a tcpdump command like this to look for the traffic:
tcpdump -ni 0.0 -Xs0 host CLIENT_IP or host POOL_MEMBER1_IP or host POOL_MEMBER2_IP
