I can’t count how many times I’ve seen the topic of WCCP in the Cisco support forums where people want to use their Ironport WSA to block traffic from internal users *and* DMZ servers. This clearly DOES NOT WORK, but I’ve never seen a very good explanation of why it doesn’t work. This is my attempt to explain why this DOES NOT WORK.
