sub vcl_recv {
(...)
        # Allow purging if backend is healthy
        if (req.backend.healthy) {
                if (req.http.Pragma ~ "no-cache" ||
req.http.Cache-Control ~ "no-cache") {
                        purge("req.url == " req.url " && req.http.host
== " req.http.host );
                }
        }
