I just had a look at this issue and can't reproduce it, nor do I see any
good reason for why it would happen based on what you provide.

Varnish can/does cache 302s, but that wouldn't explain why they are there
in the first place. The varnishlog you provide does have any Location:
header that links to Google, and after running through the list, none of
those sites refer to Google either. And I can promise you that Varnish does
not have any ties to Google out of the box.

How consistently does this happen? What other systems are involved
(loadbalancers,etc)? What sort of pattern do you see when it does happen?
If you can reproduce it, seeing output from GET/HEAD and/or firebug might
help reveal the underlying issue too.
