caddy-silence

Tells Caddy to shut up.

When plain HTTP requests are issued against HTTPS servers, the Go standard library will emit the following response:

HTTP/1.0 400 Bad Request

Client sent an HTTP request to an HTTPS server.

This module eliminates this response entirely by closing the connection when it detects that a plain HTTP request has been sent to an HTTPS listener.
