Image from store Varnish Cache Efficiency
Description from store The Varnish Cache Efficiency Extension is useful, if you want to check how many of the request necessary for the current page are delivered by a Varnish Cache Proxy. The shown number is a percentage value which says how many percent of the requests are delivered out of the Varnish Cache. To function the Varnish Cache Proxy needs to be returning the "X-Varnish" Header. More features are yet to come!
Latest reviews (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 Fernández: 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!
