How do I show a 403 error page when the server returns a 403 error code?

Question

I use the nginx config file from https://www.nginx.com/resources/wiki/start/topics/recipes/drupal/

It has return 403 and deny all on some file.
Ex. When I visit /core/CHANGELOG.txt, nginx returns default 403 Forbidden page.
I want it to display drupal 403 error page not nginx white default 403 page.

I have tried adding error_page 403 /403 but it returns

Not Found

The requested URL "http://mysite/core/CHANGELOG.txt" was not found on this server.

Answer 1

What you need to do is to configure nginx to serve a drupal page that generates a 403 page. There are severals ways to do this.

The easy solution is to route the traffic to Drupal (the index.php file), which would generate a 404 since the page doesn't exist in Drupal.

I think doing

location ~* \.(txt|log)$ {
  try_files @rewrite
}

should accomplish this for .txt and .log files. It should try to serve the file from Drupal. By default this will be a 404, but you can add the a route for specific files and return 403 instead.

From @googletorp and my google I found this solution

I added error_page 418 = @blablabla; return 418;.

location ~* \.(txt|log)$ {
    allow 192.168.0.0/16;
    deny all;
    error_page 418 = @blablabla; return 418;
}

location @blablabla {
    rewrite ^ /blablabla break;

    proxy_pass       http://localhost;
    proxy_set_header Host      $host;
    proxy_set_header X-Real-IP $remote_addr;
}

This will return to 404 page as /blablabla is not found.
