'tp

Putting the tee in HTTP.

This acts as a reverse proxy and tees responses into S3 for semi-permanent storage. It's intended to be used with Varnish as a secondary backend (to serve up and populate S3 misses).

Purging the S3 Bucket

This will empty the configured S3 bucket of everything:

foreman run node bin/purge.js

It's intended to be used when cached content is being refreshed, before Varnish is purged.

  "/background/": {
    "origin": "http://background.example.com"
