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?
