+# Auto-enable Local HTTP Caching in Test Kitchen
+
+**Note:** total experiment and hack, looks nasty, could be awesome:
+
+## Setup
+
+* Drop the `kitchen.local.yml` into `$HOME/.kitchen/config.yml`
+* Install [polipo](http://www.pps.univ-paris-diderot.fr/~jch/software/polipo/) (with Mac: `brew install polipo`, with Ubuntu: `apt-get install polipo`)
+* Drop `polipo-start` and `polipo-console` somewhere useful (perhaps `$HOME/bin`?)
+
+## Run with HTTP Caching Proxy
+
+Simply start up polipo in the foreground in a terminal/tmux/screen session with: `~/bin/polipo-start`. In your Test Kitchen project verify that caching is enabled by running `kitchen list --debug` and look for the `http_proxy` and `chef_omnibus_url` config options.
