Think it in this way....
"inbound" means:
redirect all "inbound" traffic on
this interface to the cache engine(s)
"outbound" means:
redirect all
"outbound" traffic on this interface to the cache engine(s).
When you
configure WCCP on outbound direction you can exclude from redirection some
ingress interface using the "redirect exclude in" intf command.
What it means
is the following:
"redirect to the cache engines all traffic outbound
interface X, except if it was received on interface Y"
Hope this helps

The redirect is
always from the perspective of the router. So follow the
packet (location of
the cache is mostly irrelevant for this).
User ------> (fa0/0) Router (s0/0)
----> Internet
As a user makes the request, AT the fa0/0 interface, this
would be inbound.
The same packet at the s0/0 interface would be outbound.
Make a choice!
It's useful in case there are multiple interfaces on your
router (with
users) and you want to redirect some but not others. Just one
redirect is
necessary though.
I believe about 8-9 months ago there was a
fairly detailed discussion about
web caching and the actual packet flow on
here if you want to search the
archives.

Group,
I am a little confused by the
DOC on wccp. If I have a web cache system
downstream on R1's E1 interface,
would my redirects be inbound or outbound?
From the DOC I get the impression
that the redirect command might mean what
flow of traffic do I want to
redirect. For example, If I have traffic
coming in on E0 and my web cache
system is out e1, I would "redirect inbound
on E0"...But I always thought the
redirect was suppose to point to the cache
system. In this case there would
be a "redirect outbound" on E1. Did I mis
read the doc?
