I think you can do that with:
ttl_pattern ^http:// 0 20% 43200
Without LM I would take 0 as the TTL ... right?

Yes - this would help. We also could take the Date: (if any) and
calculate the time from now to date in relation to the defined TTL -
if not 0 offcourse.
One of the silly pages from netscape had have no LM and no date ->
never cache such pages.
