In NGINX, Arabic URLs do not redirect to 410 pages (status code) but English URLs redirect to 410 pages correctly

We have a website and a website with Arabic and English addresses. We need to redirect some URLs with a 404 status code to a 410 status code in the NGINX web service (due to SEO). We configured the NGINX web service and added Arabic and English URLs, English URLs successfully redirect to status code 410 (NGINX error page), but the redirection of Arabic URLs does not work and gives users a 404 error page The final show. My question is why redirecting Arabic URLs doesn't work, since the configuration of the two types of URLs (Arabic and English) is exactly the same.

Example URLs: https://example.com/test And https://example.com/تست

NGINX configuration file:

map $request_uri $is_retired_url {
      including /etc/nginx/conf.d/redirects/410.redirects;
}

server {
           if ($is_retired_url) {
        return 410;
           }

Contents of file 410.redirects:


/test 1;
/تست 1;

Also, I encoded Arabic URLs with https://www.urlencoder.org/, but it doesn't work.

The file 410.redirects contains bidirectional text which initially made the question difficult to understand, but that is not the fundamental problem.

The variable $request_uri contains the original request as received by Nginx from the browser. Although the browser will show a URL containing Arabic text, what is actually transmitted is a URL containing url-encoded characters. For example, the Arabic text in your question appears in $request_uri as:

/%D8%AA%D8%B3%D8%AA

Nginx has another variable called $uri which is initially set to a normalised version of $request_uri. Part of the normalisation process is decoding url-encoded characters back to their original form.

Your existing 410.redirects file will work if you change the map from $request_uri to $uri.

For example:

map $uri $is_retired_url {
    including /etc/nginx/conf.d/redirects/410.redirects;
}
