[squid-users] Squid and WCCP hardware placement

[Johnson, S]

I'm working on getting this working but I'm unclear on the hardware placement 
for each of the devices.

Is it:

A)
Workstation--------->Cisco----->Squid------>internet
                            (WCCP)    (NAT)

B)
Workstation--------->Cisco (WCCP)
                        |
                       ---->Squid------->internet
                            (NAT)

C)
Workstation--------->Cisco--------->Internet
                        |    (WCCP)
                       ---->Squid

D) or???

Thanks a bunch.
