Dead easy! I've just done it for our proxy - some of our users know
best and hard code the proxy details into their browser instead of using
the autoproxy config script. Try this:

acl lan_dst dst "/etc/squid/acl/lan_dst.dst.acl"
http_access deny lan_dst
deny_info http://webserver.example.com/proxy/ lan_dst

lan_dst.dst.acl contains:

172.16.0.0/16
172.18.0.0/16

etc.

The page they get to see gives them step by step instructions on
configuring their proxy correctly!

HTH,
