Add X-Robots-Tag to all hosts.

[cowpiebrownrice]

I installed a Nginx Reverse Proxy via docker.
I would like to add X-Robots-Tag to all hosts. I tried adding the option:

add_header X-Robots-Tag "noindex, nofollow, nosnippet, noarchive";

in Advanced / Custom Nginx Configuration
but it doesn’t work.
I read that the add_header options if not included in a custom location do not work.

What custom location can I use? Or does anyone know another way to make it default?

I had a similar issue, but it was related to security headers.

I added my security headers under Proxy Hosts → Edit → Settings → Custom Nginx Configuration. These directives are added to the server { } block.

However, the location / { } block has include conf.d/include/proxy.conf, which contains:

add_header X-Served-By $host;

This overrides all add_header directives defined in the server block.

To fix it, I created a Custom Location with the path / and configured the same Scheme, Forward Hostname/IP, and Forward Port as in the Details tab. After saving the configuration, everything worked as expected.

There is a global hook for this
Every proxy host server block ends with

include /data/nginx/custom/server_proxy[.]conf;

So create /data/nginx/custom/server_proxy.conf once

add_header X-Robots-Tag "noindex, nofollow, noarchive" always;

Then restart the container and every host picks it up with no per host edits

Other hooks in the same folder if you need wider scope

• http.conf and http_top.conf for the whole http context
• root_top.conf for the main context
• server_dead.conf and server_redirect.conf for those host types

Keep always on the header or it is dropped on error responses
And remember add_header in a location wipes inherited ones so any custom location needs it repeated
