# msosorg.com now serves this docroot, so consolidate ranking signals: 301
# every other host — the old temp domain msos.spletnimojster.si, any "www.",
# and the origin host — to the canonical bare apex over HTTPS. Runs before the
# HTTPS-force below so the temp domain reaches the canonical in a single hop.

# ----- Force HTTPS everywhere -----
# Redirect any plain-http request to https. The two conditions together avoid
# a redirect loop when TLS is terminated by an upstream proxy (which forwards
# X-Forwarded-Proto: https while %{HTTPS} may read as off).

# rule above, this only runs on https://msosorg.com, so it stays relative.
