Hi!
Following will add possibility to expand $HTTP_HOST to the HTTP
Host header in "block return".
In my setup I have relayd on port 443 and httpd on 80. This patch
allows me to redirect http(httpd) to https(relayd) without knowing
the host.
/etc/httpd.conf:
server "redirect" {
listen on * port 80
block return 301 "https://$HTTP_HOST$REQUEST_URI";
}
