I have a doubt on Access-list for WCCP redirection.

I have enabled WCCP and applied the redirect in statements on the interfaces without defining any access-list to intercept the traffic.

Here is the config :

ip wccp 61
ip wccp 62

interface GigabitEthernet0/1
 description GM056980 Offnet() FRO2005696774VRP(2005696694)
 bandwidth 20000
 ip address 10.3.137.134 255.255.255.252
 no ip proxy-arp
 ip wccp 61 redirect in
 duplex full
 speed 100
 no cdp enable
 no mop enabled
 service-policy output QOS-SHAPER-GI0/1

interface Vlan1
 description GM056980 Customer LAN - L3
 ip address 208.49.97.153 255.255.255.248 secondary
 ip address 10.60.1.1 255.255.252.0
 ip helper-address 10.60.1.10
 ip helper-address 10.1.1.52
 ip helper-address 10.3.1.28
 no ip proxy-arp
 ip wccp 62 redirect in
 ip flow ingress
 ip flow egress
 vlan-id dot1q 1
  exit-vlan-config
 !

Now the question is : what will happen if i haven't define any access-list. Will Router redirect all the Traffic to Cache device or will it not deny entire traffic to redirect it to the cache device.

I know it could be very silly doubt , but this information can be helpful for me in troubleshooting the issue which i am facing.
