See if the loaded page was a cache HIT or MISS.

Image from store Cache Hit or Miss
Description from store For websites using a reverse proxy such as Varnish an icon is displayed in the address bar showing if the loaded page was caches HIT or MISS. The server must be configured to output HIT and MISS HTTP headers. This extension is only intended for developers working on sites using Varnish or another reverse proxy. It is simply a quicker way to see when a cache HIT has happened without needing to manually check the response headers.. To function the cache server must be returning at least one of the following headers: * X-Cache * X-Varnish-Cache Sites currently displaying these headers production include: * http://dyn.com * http://www.economist.com * http://www.macrumors.com * http://soundcloud.com/ * http://www.examiner.com/

  • (2020-02-09) Richard Shea: No indication of HIT/MISS, nor does the documentation state how to. Tried the URLs in documentation as a test, still no idea if it's a hit or miss, waste of my time.
  • (2019-04-09) Amna Latif: unABLE TO SEE WEATHER THE CACHE HIT OR MISS
  • (2016-09-09) David Martinez: Very useful for our Opennemas.com cache system
  • (2016-01-13) Levi Durfee: Simple and very useful! :)
  • (2013-10-23) Andy Feliciotti: Fantastic just what I needed, already had the header in place :)
  • (2013-07-16) Edouard Cunibil: Great ! Could we have some options to add headers to listen ? For example, Drupal use X-Drupal-Cache for its internal cache.
  • (2012-11-11) Peter Arato: Love it, it's pretty useful tool to check caching states without looking at the headers :)

    Hi My hosting people said that Varnish cache activated for my website https://wpdiv.com But when i test my site using your chrome extension, there is no such evidence there. Is my site is really activated with varnish cache?
