You could try setting up normal routing and abandon WCCP.

 * Place the Squid box(es) outside the router (closer to the Internet)
 * At the Cisco route port-80 from the clients through the Squid, other
traffic direct to the Net
 * Squid connect direct to the Net (most efficient) or if they must go
through the Cisco again, they must be specially exempted from the
redirection.
