[squid-users] WCCP and ICP

Hello,

I have 2 cache servers and use WCCPv2. I don't think i need to use ICP
as WCCP would control what sites go to what servers so that a request
for the same URL would always go to the same server, but can someone
confirm this?
Secondly, if I should be using something like ICP, should I be using
HTCP, cache digests, etc?
