Hi
The redirection has nothing to do with where the cache is. When you
configure wccp it creates a session with the cache and negotiates
certain features, which as far as I know are irrelevant to the lab.
So the steps to it are:
(global) ip wccp web-cache
***there are a few self explanatory commands here which all have to do
with the session created with the cache***
(interface) ip wccp web-cache redirect in/out
*** this is an interface command. There are two ways to do it. First way
is to put it on the interface attached to your clients doing the
browsing (using in keyword). Second is to put it on the interface
attached to your ISP (using the out keyword) ***
Remember the commands need to be looked at from the routers perspective.
The redirect command will redirect browser requests ie stuff going to
TCP 80.

Duane

Subject: IE Lab#11: WCCP
Objective: Have the HTTP requests redirected to the web cache engine
located in VLAN 3.
My limited knowledge on WCCP leads me to believe that you direct either
the in or out keyword with the "ip wccp web-cache redirect" interface
command based on the direction of the HTTP request (where the web cache
engine is).
I'm looking for a WCCP guru here to help point me in the right direction
(no pun intended). My question here is the direction you apply the "ip
wccp web-cache redirect" command. I would think that if VLAN 3 hangs
off of E0/0 on the router being configured and that is where the web
cache engine is located, you would apply it outbound ("ip wccp web-cache
redirect out") on the E0/0 interface towards the web cache engine and/or
inbound if applied on the other interfaces ("ip wccp web-cache redirect
out") on the interfaces on the router. One more thing to throw you in
the mix. The users are also hanging off of E0/0 as well. In that case,
would you need to change the direction on E0/0 to "in" to have the
direction point back to the web cache engine on that VLAN or is it still
applied with the "out" keyword on E0/0.
Help!
