varnish storage tuning

[Mike Perham]

Does restart cause the backend to be queried for the page again?  I'd prefer
if a purge did not re-fetch the URL from the backend as this can caused
unwanted content to stay in the cache and my cache is relatively limited in
size.  Can I do something like:
sub vcl_hit {
    if (req.request == "PURGE") {
        set obj.ttl = 0;
        error 200 "Purged";
    }
}

sub vcl_miss {
    if (req.request == "PURGE") {
        error 200 "Purged (not in cache)";
    }
}
