  .port = "8080";
  .connect_timeout = 600s;
  .first_byte_timeout = 600s;
  .between_bytes_timeout = 600s;

sub vcl_recv {
  if (req.request != "GET" &&
    req.request != "HEAD" &&
    req.request != "PUT" &&
    req.request != "POST" &&
    req.request != "TRACE" &&
    req.request != "OPTIONS" &&
    req.request != "DELETE") {
      # Non-RFC2616 or CONNECT which is weird. */
      return (pipe);
  }

  if (req.request != "GET" && req.request != "HEAD") {
    # We only deal with GET and HEAD by default */
    return (pass);
  }

  # Remove has_js and Google Analytics cookies.
  set req.http.Cookie = regsuball(req.http.Cookie, "(^|;\s*)(__[a-z]+)=[^;]*", "");
 
  # Remove a ";" prefix, if present.
  set req.http.Cookie = regsub(req.http.Cookie, "^;\s*", "");
  # Remove empty cookies.
  if (req.http.Cookie ~ "^\s*$") {
    unset req.http.Cookie;
  }

  if (req.http.Authorization || req.http.Cookie) {
    # Not cacheable by default */
    return (pass);
  }

  # Skip the Varnish cache for install, update, and cron
  if (req.url ~ "install\.php|update\.php|cron\.php") {
    return (pass);
  }
  
  # Let's have a little grace
  set req.grace = 30s;
