Quick update on this a year later: this is the Varnish 4.1/5 Discourse config I’ve been using that appears to work without any issues:

```plaintext
if (req.http.host ~"discourse.bigdinosaur.org") {
   if (!(req.url ~ "(^/uploads/|^/assets/|^/user_avatar/)" )) {
      return (pass);
   }
}

```

Could probably also tweak it a bit, since it’s ignoring and not caching some emoji (specifically emojii with query strings on the end of their URLs) and a couple of other things (scripts, css). But it works!

edit - this is in `sub vcl_recv`, obviously.
