Something of an infinite loop. Do you mean no access to the internet or to the proxy? If you mean no access to the internet you could use WCCP on a router that sits somewhere along the default route path to intercept the request and send it to squid where you would have an ACL that captures the requests and presents the failure page. I think we need more info - are you using interception/proxy.pac etc
