Nginx configuration:

location = /xxx {
  return 301 /qwerty;

Expected result:

GET http://localhost/xxx contains header Location: /qwerty

Actual result:

GET http://localhost/xxx contains header Location: http://localhost/querty

This is a problem when nginx runs behind another reverse proxy, so that nginx doesn't know the correct public hostname/port to redirect to.

See for details.

why not using:

location = /xxx {
  return 301 $scheme://$http_host/qwerty;

comment:2 by zakjan@…, 8 years ago

Because the inner nginx behind a reverse proxy doesn't know the public origin (schema, hostname, port).

comment:3 by Ilyas Bakirov, 8 years ago

Yes, nginx does not know public origin behind proxy. It only knows what in proxy scope, so yo may pass additional info with values by using optional vars

comment:4 by zakjan@…, 8 years ago

These vars can change quite often in cloud environment. It would be helpful if nginx wouldn't need to know them in this case.

Core: relative redirects (closes #1000).

The current version of HTTP/1.1 standard allows relative references in
redirects (

Allow this form for redirects generated by nginx by introducing the new
directive absolute_redirect.
