Thanks Amos for the informations.
Actually I didn't understand how could be the workaround. I already usa an "http_acces" befor the directive cache_peer_access:
http_access allow srcservers1 todomains1
http_access allow srcservers2 todomains2
cache_peer_access host11.domain.com allow todomains1
cache_peer_access host12.domain.com allow todomains2
Shoud I add some other directive if the ACL todomains1 is an IPaddress (dst) ?
Kind regards,
Daniel Hubeli

Yes. Pick one. In the current Squid it makes no sense to use both.

That is reasonable yes. In fact exactly what cache_peer_access is
designed for.

Is there some other possibilities to do that ? ... actually 99% of my ACL use dstdomain or regex but for some special needs I need to configure also URL like http://IPADDRESS/ and I'd like to have the possibility to choose the right peer.
You can sort of do it by having one of the "SLOW" group access controls
lookup the destination IP address before peer selection happens.
http_access is the best one. Also be aware that there is no *1*
destination IP - most websites these days are hosted on several
different IP addresses and you never know which the peer will choose.
