Magento可以防止Varnish缓存页面

Question

Varnish works perfect if you change the header to header('Cache-Control: public, max-age=10');.

But Magento overwrites the header with it own header: Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0, s-maxage=86400

Resulting in never cached pages. But you also don't want Varnish to cache logged in users... So how should I configure Varnish and/or Magento to cache what is necessary to cache?

Varnish 4.0 (4.0.3-1)

PHP 5.6 (5.6.24-1)

Nginx 1.0.15 (1.0.15-12)

Magento 1.9 (1.9.2.4)

Here is my HTTP header:

HTTP/1.1 200 OK
Server: nginx
Date:   Mon, 08 Aug 2016 08:46:28 GMT
Content-Type:   text/html; charset=UTF-8
X-Powered-By:   PHP/5.6.24
X-Frame-Options:    SAMEORIGIN
Cache-Control:  no-store, no-cache, must-revalidate, post-check=0, pre-check=0, s-maxage=86400
Expires:    Mon, 31 Mar 2008 10:00:00 GMT
Pragma: no-cache
Content-Encoding:   gzip
Vary:   Accept-Encoding
X-Varnish:  32770
Age:    0
Via:    1.1 varnish-v4
Content-Length: 0
Connection: keep-alive

My Varnish vcl configuration:

backend default {
  .host = "127.0.0.1";
  .port = "8080";
}
sub vcl_recv {
    unset req.http.cookie;
}
sub vcl_backend_response {
    unset beresp.http.set-cookie;
}
sub vcl_deliver {
 unset resp.http.set-cookie;
}

My "nginx.conf" configuration

There might be some block on your page that is non-cacheable. Search for ... cacheable="false" in *.xml files and consider making blocks cacheable.

It might also make sense to make sure that cache is enabled by running

bin/magento cache:status
