Hi
If F0/0 is your subnet which carries your browsers and S0 is your subnet
that goes to ISP then you have two choices:
1) redirect in on F0/0
2) redirect out on S0
Both do the same thing but are mutually exclusive (you can have only
one). If you redirect on F0/0 you reduce the load on the router because
the packets don't carry across the router and then get redirected anyway
from S0.
Regards
Duane

In other words, in on the interface facing cache server ?
Thanks

Hi
With WCCP redirection you ONLY use redirect in OR redirect out on an
interface. If you use both you will redirect return packets.
The usual config is redirect in on your closest interface to the source
traffic so that CEF can reduce the load on the router.

You should have one or the other from a technical perspective.
If you put both, then things may be confusing where the router redirects
the
previously redirected requests. (Not sure on this, as I haven't tested
it,
but it sounds like a bad idea!)

Scott
Thanks for the clear explanation :-)
For D-Day, would Cisco accept one or the other or both. Or perhaps it is
something that I need to deduct from the wording
Regards

The "redirect" is from the perspective of the router with regards to the
http request being made.
So:
User --> e0/0 (router) s0/0 --> internet web server
The web request is seen INCOMING on e0/0 and OUTGOING on s0/0. You may
put
either:
E0/0: ip wccp web-cache redirect in
S0/0: ip wccp web-cache redirect out
The location of the web-cache itself is not part of the picture for this
particular command.

Hi Group
I still find it confusing to decide the direction of re-redirection when
using caching engine.
If a caching engine is on a LAN, would I redirect out to it so it caches
my
requests ?
Or redirect in, so I accept response from it.
I am inclined to use 1st explanation.
Any thoughts ?
TIA
Sam
