Why doesn't timeout work in location?

Question

Nginx

Why doesn't nginx change timeout values ​​for a specific location?

location /example {
      proxy_read_timeout 5s;
      proxy_connect_timeout 5s;
      proxy_send_timeout 5s; 
      try_files $uri $uri/ /index.php/exl?$query_string;
}

If you put return 500 there, it will return an error, which means that the location itself is seen as a priority. But the execution time is still more than 5 seconds...

Answer 1

location /example {
    try_files $uri @backend;
}

location @backend {
    proxy_read_timeout 5s;
    proxy_connect_timeout 5s;
    proxy_send_timeout 5s;

    rewrite ^ /index.php/exl break;

    proxy_pass http://backend;
}

Or

location /example {
    proxy_read_timeout 5s;
    proxy_connect_timeout 5s;
    proxy_send_timeout 5s; 

    rewrite ^ /index.php/exl break;

    proxy_pass http://backend;
}

Answer 2

Because, obviously, the request in accordance with try_filesleaves for some other location, where the timeouts are different.
