Set up a profile in /etc/xinetd.d called http:
# default: off
# description: Poor man’s http server that simply issues redirects.
flags = REUSE
socket_type = stream
wait = no
user = root
server = /bin/echo
server_args = -e HTTP/1.1 301 Moved Permanently\r\nLocation: https://somewhere:8443\r\n
disable = no
(Re-)Start xinetd and now you have a simple redirect server – no httpd or other web server required.
