varnish giving error 503

[Mike Franon]

Hi,

I am trying to get varnish up and running super fast for a production
website, we are hammered.

We only want to cache one URL, that is being hammered, and pass
everything else through, I know this is a just a simple config, but is
there anything I am missing to get a 503?  Is it because our servers
are being hammered that it is not even able to get pages to cache?


sub vcl_recv {

  # set default backend
  set req.backend = default_director;





  # lookup stylesheets in the cache
  if (req.url ~ "^/Tree") {
    return(lookup);
  }

  return(pass);
}


sub vcl_fetch {
  if (req.url ~ "^/Tree") {
    # removing cookie
    unset beresp.http.Set-Cookie;

    # Cache for 1 day
    set beresp.ttl = 1d;
    return(deliver);
  }
