I have a Blue Coat appliance in place in my network. If the b/c goes down the internet will not be available. Does WCCP correct this issue and if so how?
If all requests to the Internet are already going via your bluecoat then you do not need to use WCCP at all.
By fail open Edison means that if the bluecoast stops working it still passes traffic.
You have no use for WCCP in this instance.
