Varnish only takes into account max-age

gonzalovilaseca · gonzalovilaseca · commit f958391bb74c · 2014-06-11T15:45:24.000+01:00
Varnish only takes into account max-age, Symfony by default returns Cache-Control: no-cache so Varnish caches it anyway. You need to specify:
```
if (beresp.http.Pragma ~ "no-cache" ||
             beresp.http.Cache-Control ~ "no-cache" ||
             beresp.http.Cache-Control ~ "private") {
    return (hit_for_pass);
}
```
In order to avoid Varnish from caching content.
