If the port is not 443 for HTTPS (as checked by (std.port(server.ip) != 443)), the subroutine will set the request HTTP Location header (set req.http.location) to a secure request (“https://” + req.http.host + req.url) simply asking the web browser to load a HTTPS version of the web page (i.e URL redirection). The connection between Hitch and Varnish can be done over Unix Domain Sockets, which further reduces latency. Open a web browser and use your domain or server’s IP to navigate over HTTPS. The default configuration is to listen on all IPv4 and IPv6 interfaces attached on the server and runs on port 443 and handle incoming HTTPS requests, handing them off to Varnish.
