AFAICS squid will cache the entry anyway and use it for a grace period.
Setting grace=0 should block that.

if you are happy to test it I have placed a patch at
http://treenet.co.nz/project/squid/patches/extacl_noncaching.patch which is
supposed to make Squid obey ttl=0 and negative_ttl=0 like expected.
 Note that this will prevent external ACL results from being used by any
of the FAST category access controls in the non-cached entries.
