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/

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.

Very useful for our Opennemas.com cache system
Levi Durfee
Simple and very useful! :)
Andy Feliciotti
Fantastic just what I needed, already had the header in place :)
Edouard Cunibil
Great ! Could we have some options to add headers to listen ? For example, Drupal use X-Drupal-Cache for its internal cache.
Peter Arato
Love it, it's pretty useful tool to check caching states without looking at the headers :)
