How do you confirm cookies are removed from static files?

[Felix Hanley]

The client will request that cookies be set and there is not much you
can do about that, except unset them. But they will still be in the
request.

The line in vcl_recv will remove set-cookie headers from the request.
The line in vcl_fetch will remove cookie headers before being stored in
the cache.

Your code looks fine. To confirm it is being stored, you will need to
use varnishlog or something.
