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.

Wow, it looks like you're right (https://www.varnish-cache.org/docs/3.0/tutorial/increasing_your_hitrate.html#cache-control).

What do you think about adding a little note in your comment that says that Varnish ignores the no-cache by default and include the link from above? I want to leave "breadcrumbs" for readers later when they see this.

Done!

could you please put the url on a new line? That way, people don't have to do the quirckly horizontal scroll & select thing to select the url.
