Extension Usage Instructions

                        An icon will advise if Varnish is being used, and if so, if the page was served from cache or not.

You should install this if you're a developer and want to quickly determine if a page was served from Varnish cache.

The icon has four status colors:

- Gray: the default, displayed when Varnish isn't detected.
- Blue: displays when Varnish is detected.
- Green: displays when the page was served from cache.
- Red: displays the when the page wasn't served from cache.

It looks for x-varnish and x-varnish-cache headers to detect Varnish. It can inspect both the x-varnish-cache (looking for hit and miss) and x-varnish (looking for two ids) headers to determine if a hit or miss took place.

The extension is open source and you can find more details at https://github.com/smebberson/varnish-indicator-extension.

Improvements and suggestions are welcomed :)
