Adding Clack Overhead to Nginx

To add the X-Clacks-Overhead header in Nginx, the add_header directive in the Nginx configuration file can be used.

1. Locate the Nginx configuration file.
2. Open the configuration file in a text editor with administrative privileges.
3. Add the following line in the http block:

   add_header X-Clacks-Overhead "GNU Robbert Muller";
   

4. Save the changes to the configuration file.
5. Restart Nginx to apply the changes by running service nginx reload, nginx -s reload, systemctl reload nginx, or similar command.

At this point the header should be added to all responses served by Nginx. To check, see the "How to verify" page.
