[squid-users] ACL distinction between ".domain.tld" & "domain.tld"?

[Steve Snyder]

For purposes of defining an ACL in Squid v2.5S1, is there a distinction 
made between ".domain.tld" and  "domain.tld" (note the leading dot in the 
first case)?

For example, if I say:

        acl slashdot dstdomain slashdot.org
        no_cache deny slashdot

(note absense of leading dot) will that still leave objects from 
*.slashdot.org cacheable?

Thanks.
