Hello!

I?m sorry I miscommunicated to you, I told u about HTTP/1.1 because
your header says: 'Cache-Control: private, max-age=0, must-revalidate'
and varnish should respect cache requests with private or max-age=0.

I suggest you the following vcl:

# for security reasons :)
acl header {
        "localhost";
}

# vcl_deliver

sub vcl_deliver {
        if (obj.hits > 0) {
                set resp.http.X-Cache = "HIT";
        } else {
                set resp.http.X-Cache = "MISS";
        }

        if (client.ip ~ header) {
                set resp.http.X-Served-By = server.hostname;
                set resp.http.X-Client-IP = client.ip;
                set resp.http.X-Cache-Hits = obj.hits;
        } else {
                unset resp.http.X-Server-ID;
        }

        # set resp.http.X-Cache-Hits = obj.hits;
        set resp.http.X-Age = resp.http.Age;
        unset resp.http.Age;

        remove resp.http.X-Varnish;
        remove resp.http.Via;

}


And try:

$ curl -I -H "Host: www.yourdomain.com"
http://localhost/upload/canal/22/topo.jpg
