http://www.isvarnishworking.com/ saying "no varnish " why?

[TOMER628]

hi !

i using your Default.vcl ..
i checked in http://www.isvarnishworking.com/ website, if my varnish (4) working..
and he said " NOPE ! "
how this possible ?

here my config details:

let say my server ip is :123.123.123.123

so this my configuration of Default.vcl:

backend default {
.host = "123.123.123.123";
.port = "8080";
.connect_timeout = 600s;
.first_byte_timeout = 600s;
.between_bytes_timeout = 600s;
.max_connections = 800;
}

Only allow purging from specific IPs

acl purge {
"localhost";
"127.0.0.1";
}

and in Nginx.conf :

server {
listen 123.123.123.123:80;
server_name mydomain.com www.mydomain.com;
error_log /var/log/httpd/domains/mydomain.com.error.log error;

location / {
    proxy_pass      http://123.123.123.123:6081;

    proxy_cache cache;
    proxy_cache_valid 15m;
    proxy_cache_valid 404 1m;
    proxy_no_cache $no_cache;
    proxy_cache_bypass $no_cache;
    proxy_cache_bypass $cookie_session $http_x_update;

    location ~* ^.+\.(jpeg|jpg|png|gif|bmp|ico|svg|tif|tiff|css|js|htm|html$
        proxy_cache    off;
        root           /home/admin/web/mydomain.com/public_html;
        access_log     /var/log/httpd/domains/mydomain.com.log combined;
        access_log     /var/log/httpd/domains/mydomain.com.bytes bytes;
        expires        max;
        try_files      $uri @fallback;
    }
}

location /error/ {
    alias   /home/admin/web/mydomain.com/document_errors/;
}

location @fallback {
    proxy_pass      http://123.123.123.123:6081;
}

location ~ /\.ht    {return 404;}
location ~ /\.svn/  {return 404;}
location ~ /\.git/  {return 404;}
location ~ /\.hg/   {return 404;}
location ~ /\.bzr/  {return 404;}

include /home/admin/conf/web/nginx.mydomain.com.conf*;

}

i think this configurated correct. so why http://www.isvarnishworking.com/ say no varnish ?

Nope!
We didn't find the "X-Varnish" header in the response from the server so likely Varnish is, in fact, not working.

Shoot.

It is possible that the Varnish daemon is technically running on the server, but maybe listening on another port. It's also possible someone modified the headers in your Varnish installation - in which case you're out of luck pal!

And here, for you to ponder further, are the actual headers we received:

The url we checked: mydomain.com
HTTP/1.1 200 OK

X-Cache: cached

And the headers we sent:

HEAD / HTTP/1.1

Check another site!

Varnish cache server

Your server needs to listen on 127.0.0.1 to or the nginx won´t be able to resolve the request from Varnish to the correct domain.

X-Cache: cached, tells you already that the page cache (varnish is working correctly)or was lol.

That´s what you need to see, because in the default vcl they removed all "mentions" of varnish (preventing website scans from Bots for security holes for example)

And I´m not sure for what the Proxy pass is? You go through Varnish, than to nginx than to..? .. Something else?
