A simple Google Chrome extension that shows if a page being served up via a Varnish web accelerator is fresh or not.This is a fork from https://github.com/deizel/varnish-inspector, so he deserves much of the credit. I've improved this to work with different flavors of Varnish (the original had a dependency on the order of headers). In particular, I've been testing this with Fastly, a CDN that uses Varnish under the hood.
