Mike,

There was a good post a while back that explained WCCP direction. Think of
the redirect direction from the routers perspective.
See the simple diagram below

example showing the "in" direction

Destination--E0--Router--E1--Client
                       |
                     E2
                       |
           Cache Engine
!
interface Ethernet0/1
ip address 10.10.100.6 255.255.255.0
ip wccp web-cache redirect in
!

another one that shows how to use the "out" direction

                Non Client
                        |
                      E3
                        |
Destination--E0--Router--E1--Client
                        |
                      E2
                        |
             Cache Engine
!
interface Ethernet0/0
ip address 10.10.254.1 255.255.255.0
ip wccp web-cache redirect out
!
interface Ethernet0/3
ip address 10.10.100.1 255.255.255.0
ip wccp redirect exclude in
