If I wanted to intercept all server requests that aren't https, and aren't prefixed with www, and redirect to the <https://www>. version of my site - what would be the best way to do that?

[gildor]

I would do this on proxy/balancer level

There are of course many solutions to this problem; but I found 'Traefik' to be an excellent fit:

Highly configurable and light HTTP (Reverse) Proxy that will also help you with TLS termination & HTTPS redirects.

Sure - that's if your project has a proxy / balancer though. I need to do this with ktor.

I wouldn’t say that it’s “the best way”, but what is problem to do that with ktor just by writing own interceptor?
