I'm convinced WWW-wide spiders are a pretty bad idea anyway, for more
reasons than the infinite dynamic page problem.
If you run the spider on your own server you know what URL's to avoid,
so there is no problem.

I really don't see why a human cares? And I can imagine that spiders
don't always care either. Say I have a welcome page that is dynamic 
and displays the date and local time or whatever, I'd still want my
robot to use it. And most ISINDEX servers can be regarded as dynamic
