The reply at the link says to configure a rule for "no-cache". This will not prevent the CE from making the request, it only tells the CE to not Cache it.
Reading the question, I am not sure of exactly what the request is, but if the goal is to have the client go directly to the server, there are multiple ways to do this.
If you want the client to make the connection to the site, you can you a redirect list on the WCCP router
In the following example, traffic to 172.18.124.193 will not be redirected to the CE, but will go directly to the server.
router# configure terminal
router(config)# ip wccp web-cache redirect-list 120
router(config)# access-list 120 deny ip any host 172.18.124.193
router(config)# access-list 120 permit ip any any
Or, you can create a static bypass entry on the CE using the bypass command. Bypass, like the router redirect list, requires the use of WCCP.
