Sorry, but I don't see your point.
An user who doesn't encrypt traffic end-to-end implicitly trusts all
nodes that interconnect her to the origin server not to mess things up
relatively to the sensitivity of the exchanged information. This means
her PC, the firewall, the proxy, network switches, origin servers and
content providers and so on.
Any node along the chain could theoretically hijack traffic and steal
her identity or perform actions on her behalf.
In this regard I see the ICAP server not to be any different from a
proxy server, of which it is simply an extension. I just fail to see any
added security in not sending all the information that the proxy server
has to the ICAP server.
