Bypass proxy for static files

[adriaant]

Is it already possible to create the following in the "location / {}" specification of a vhost? It is not clear to me.

        # Try to serve static files from nginx, no point in making an
        # *application* server like Unicorn/Rainbows! serve static files.
        if (!-f $request_filename) {
            proxy_pass http://foo_server;
            break;
        }

Using a different way to config nginx with gunicorn. The above rule is not necessary if you use a 'root' config for static files.
