Question

With Nginx, I intercept 404 errors for some JS file in a folder, and redirect to a PHP script that try to create / return the good file, with response code 200 in case of success.

But Nginx continues to write in error.log because the first attempts return a 404 header.

Can I disable this writing if the redirection leads to a 200 response code ?

My configuration in Nginx for these files :

    location /assets/js/minified/ {
            error_page 404 /index.php?controller=404&action=create_js;
    }

Thanks !

I guess try_files is a better fit for your use case

location /assets/js/minified/ {
  try_files $uri /index.php?controller=404&action=create_js;
}

See the documentation

Otherwise (in case you don’t like try_files for any reason), there is log_not_found directive that disables writing 404s into error.log.
