Sorry, I should have done a better job explaining.
I know nothing about javascript, but Google doesn't seem to pass the
URL in a variable. It's as simple as this:
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script>
Even if it were passed in a variable, modifying the code would violate
Google's Terms of Service, and from what I've read they're very strict
about it.
As for the Robot* directives, it sounds like it's still a good idea to
use them, even with mv_no_session in place. I'm still trying to come
up with data on what percentage of users reject session cookies these
days.
