Garnish - simple varnish implementation written in Go

The varnish is a well-known HTTP accelerator. As the continuation of the GoInPractice series, today I’ll show how you can build a simple (and naive) varnish implementation in Go. Some of the code is reused from Writing a reverse proxy so if you don’t understand something, I recommend taking a look at the blog post. We’ll split our project into a few parts. The first one will be the caching mechanism.
