  • (2016-03-11) My favorite extension for chrome - excellent for testing Varnish implementations, when used in conjunction with F12 developer tools gives a really good picture of what went into serving the request. Recommended.
  • (2015-06-24) Julio Fern├índez: It doesn't work for me. 59 servers tested so far. Worst is the support/documentation. No info online. It must be a configuration problem, but for me it's just useless as it is. No thanks.
  • (2015-06-17) Kevin Clarke: Great. A nice addition would be to see which resource requests were not cached.
  • (2013-01-07) Rene Rothauer: :D
  • (2012-12-17) Daniel Kuster: Really useful!

  • (2016-03-02, v: Nemam pojma Francesc: With Cloudflare
    I think this extension is not working when Cloudflare is present. Maybe it gets confused by Cloudflare headers. If I deactivate Cloudflare in my site, looks alright, but with cloudflare on, nothing happens. The other option is that Cloudflare also forces on my site to be https, might that be it?
