Homelab from GCS

I have a little blog (you’re reading it) and it was served from static files with caddy on a little GCE VM. I recently decided to reimplement it using GCS, in part because I was running out of disk space. Approach:

1. Requests go into caddy.
2. Caddy proxies requests to a trivial GCS server that reads the data, including content type and last modified, from GCS and serves it as a http request.

The server supports range requests, by opening the object and seeking within it to the data.
