Sorry, I mis-spelled the quote.
You said earlier before I joined the thread that you "when I negate
ICAP for some ACL it bypass cache_peer too" (cut-n-paste this time :-)

I must be going blind. An idea just occurs to me:

    always_direct allow sites_no_authentication
means bypass any peers and go direct for 'sites_no_authentication'

    never_direct allow all
means NOTHING can go direct, use peer or fail.

If this idea is right, then the always_direct is kicking all the peer
logics aside and forcing it to go direct before the never_direct gets
tested.

Try this:
   always_direct deny sites_no_authentication

or remove the line and finish with:
     always_direct deny all
