La redirection nginx échoue si la demande d'origine n'existe pas

Énoncé du problème : nginx ne semble pas rediriger lorsque la demande d'origine concerne un emplacement inexistant. Toutes les autres redirections semblent fonctionner correctement. Il est également possible que php n'exécute pas le script sur la page redirigée. nginxconf est fourni ci-dessous.

Question : Qu'est-ce qui me manque et que dois-je faire pour que cela fonctionne ? Est-il possible que nginx ne prenne pas en charge la redirection à partir d'une page qui n'existe pas ?

Un peu de contexte peut aider : Voici une demande typique redirigée : 

73.234.24.22 - - [30/May/2022:16:15:05 +0000] "GET /postevent3.asp?dta=05%2f30%2f22%2016%3a15%3a22%20507%20%2b149642656%20%2d254084882%20%2d0001787%20682829361 HTTP/1.1" 302 154 "-" "-"

Notez qu'aucune page n'est affichée pour cette requête ; la requête est vidée dans un tampon, traitée et écrite dans la base de données. Voir la fin de cet article pour un extrait du journal de débogage nginx.

Changer l'URL n'est pas pratique car il existe des dizaines d'unités dispersées dans le monde. La plupart des appareils ne peuvent pas être mis à jour à distance.

Le site d'origine n'est plus utilisé, utilisant Apache. Le site actuel utilise nginx. Je ne suis pas très familier avec les serveurs Web, donc il me manque probablement quelque chose d'évident. Toutes les idées seront appréciées.

J'ai également essayé ce qui suit dans le bloc du serveur du port 80 : 

location / {
    try_files $uri $uri/ /data/submit_legacy.php?$query_string;
}

    Si je suppose que le logiciel effectuant cette demande ne peut pas interpréter le code de redirection HTTP 302 et faire une nouvelle demande est correct, alors votre seul recours est de gérer la demande dans le bloc HTTP lui-même. au lieu de votre actuel 

    location = /postevent3.asp {
    return 302 https://example.org/data/submit_legacy.php?$query_string; 
}

    Vous pouvez vérifier cette configuration : 

    location = /postevent3.asp {
    rewrite ^ /data/submit_legacy.php break;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$uri;
    fastcgi_pass unix:/run/php/php7.4-fpm.sock;
}

    Si vous utilisez cette configuration, vos demandes commenceront à apparaître dans la base de données, ce qui signifie certainement que ma supposition initiale était correcte.
