acl mysites dstdomain www.domain1.com www.domain2.com ...
http_access allow mysites

where the default config says you should add rules allowing access from
your clients.

If you use a redirector, then add rules to this redirector telling what
should be done when the user requests by IP.

If you use /etc/hosts for forwarding to the backend servers then you need
to add a redirector to rewrite the IP based requests into something
meaningful.

If you do cache_peer based forwarding then set up cache_peer_access to
route the IPs to the correct backend web server.
