Re: transparent cisco configuration

Not true. You can set route-map and set netx-hop with mutiple ip
addresses; i.e., if first one fails, then the http traffic will go to the
second one, etc.., but once all of squid servers fail, you customers' http
traffic will be sucked into a "blachole" with no return. Any cisco cureent
stable release IOS support this.

WCCP is total different story. It deos very nice job on loadbalancing,
failover traffic, very easy to configure. Cisco really know how to handle
traffic on the routers.
