At what point in the tutorial are you seeing the message that it is not supported?

@ryanpq
when i follow that tutorial i get error at
sudo apt-get install varnish libvarnish-dev

from varnish support i followed new instruction to install varnish 4.0 which is for ubuntu 14.04 and then i was able to install varnish. then i followed again next parts of varnish configuration from the above tutorial and then i get this msg when i tried to start varnish.

root@:~# sudo service varnish restart

From Varnish documentation :

1. " vclfetch is now vclbackend_response".
2. "req.* not available in vclbackendresponse ! req.* used to be available in vclfetch, but after the split of functionality, you only have 'bereq.*' in vclbackend_response."

So with varnish 4.0 the beginning of the default.vcl file should look like this:

backend default {
    .host = "127.0.0.1";
    .port = "8080";
}

# Drop any cookies sent to Wordpress.
sub vcl_recv {
        if (!(req.url ~ "wp-(login|admin)")) {
                unset req.http.cookie;
        }
}

# Drop any cookies Wordpress tries to send back to the client.
sub vcl_backend_response {
        if (!(bereq.url ~ "wp-(login|admin)")) {
                unset beresp.http.set-cookie;
        }
}

After that Varnish started !
