Additional Thoughts

Will this handle HTTPS/SSL?

This will not cache HTTPS requests. Much like monolithic, you will need to set up sniproxy.

Why this over Monolithic?

It started with: I wanted to export metrics on my cache to Prometheus and nginx wouldn't export raw Prometheus stats for their cache. Then it turned into "This would be a fun thing to write."

Can you make it do X?
