WCCP revisited (redirect out command)

Hi all,

I know this has been discussed a lot in the past. Entering "wccp
redirect" in the Archives yields 12 results but none to answer my
question which is how to use the 'redirect out' parameter.

I've already gone through the nice example in the Cat3550 docs which
says if the topology is this:

                Internet
                   |
                   |
                 (S2/0)
Clients -- (Fa0/0)R1(Fa1/0) -- WCCP Server

then on Fa0/0, we put 'redirect in' so that clients get redirected to
the Cache engine. That's all very fine because there is no 'redirect
out' command on the Cat3550.

On a router I could do 'redirect out' on Fa1/0, OR 'redirect in' on
Fa0/0 OR both (it takes it). In other words,

interface Fast Ethernet0/0
 ip wccp web-cache redirect in
!
interface Fast Ethernet1/0
 ip wccp web-cache redirect out
end

is legitimate and taken by the CLI. What will it do? The 'show ip wccp
web-cache' command isn't terribly useful. Should I assume that I should
do either 'redirect in' on Fa0/0 or 'redirect out' Fa1/0, but should not
do both? Things would be much simpler if there were no 'redirect out'
command. Looking for some clarification on the 'redirect out' command.
Thanks.
