I think you went to "http://localhost:3000/" instead of
I'm not sure why Nginx would feel overkill while Pound wouldn't. I
would think the opposite: Nginx is a fairly well-understood piece of
technology already, with packages in most distributions, and well
known performance characteristics. I'd use it long before something
I've never heard of before.
Anyway, I think a better bet would be to provide another package like
warp-openssl, which should be a very simple venture. But considering
the fact that http-enumerator is already built on tls, it seems like
tls is doing pretty well already.
