Varnish Cache Efficiency
Extension Delisted
This extension is no longer available in the official store. Delisted on 2025-09-16.
It calculates a percentage which shows how many of the requests for this page, are being served by a Varnish Cache Proxy!
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!

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.
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.
Great. A nice addition would be to see which resource requests were not cached.
:D
Really useful!
