This is covered by the FAQ:

	http://www.squid-cache.org/Doc/FAQ/FAQ-4.html#ss4.19

	For example, if you want Squid to connect directly to hotmail.com servers,
	you can use these lines in your config file:

	acl hotmail dstdomain .hotmail.com
	always_direct allow hotmail

As for using IP address ranges into ACLs, you'll find all of the different
flavors of ACLs here:

	http://squid.visolve.com/squid24s1/access_controls.htm#acl


Since you stated that you are using squidGuard, also note that you have to
take different precautions if the domains are in your blacklist databases.
SquidGuard can manipulate the URL before squid sees it, so the squid ACLs
won't have an affect if the site is blocked. In this case, you'll have to
explicity remove the entry or explicity permit it.
