Set 'Referrer-Policy' => 'same-origin'

Installation

Hello there,

I want to set the 'Referrer-Policy header to ‘same-origin’. This can’t be done via nginx, because it’s set via Redis/Rails.

Default seems:
Referrer-Policy' => 'strict-origin-when-cross-origin'

Is it possible to change this to:
Referrer-Policy' => 'same-origin'

I could not find the string within/outside the container. :roll_eyes:

Yeah. Stupid. I was not searching at the right place.

I found many entries of
Referrer-Policy' => 'strict-origin-when-cross-origin'

Here is a list (grep strict-origin-when-cross-origin /var/www/discourse/ -R):

I really don’t know where to set same-origin. Any hints?

Very nasty hack here but

you could resolve this in nginx by adding a proxy_hide_header and follow it with your own add_header

Yeah nasty hack. Don’t like that. :wink:

Any help Herr where is the right place that is used in production?
