I've set up a test server on: http://95.85.19.39/ With varnish 4.1.5 (port 80) and nginx 1.4.6 (port 8080) running on Ubuntu 14.04. I'm using Chrome 57.0.2987.110 (64-bit).
Varnish is caching the page, but when you wait 5+ seconds and hit refresh, you'll see an initial connection, why is this? When you hit refresh within 5 seconds, there won't be an initial connection.
If I remove varnish and run the server just on Nginx then I won't get the initial connection anymore, so I assume there's something wrong with my Varnish.
Does anyone know why this is happening and how would I go about fixing this issue?
