NoDubs
A really dumb but useful HTTP redirector service.
http[s]://www.$example.com => https://$example.com for anyone who points a
www.-prefixed domain at the server's IP.
Status
This is an experiment. You absolutely shouldn't use it for anything serious.
Motivation
People have been trained to type "www.example.com", and I'm always having to add
some mechanism to redirect requests to "example.com". That used to be easy when
you had a traditional web server (apache/nginx/caddy), but has gotten annoying
in the PaaS era.
Operation
This stupid bit of software does that for you with zero configuration. You just
point www.yourdomain.com at a server running nodubs, and "Bob's your uncle", as
the kids almost certainly never say any more.
