Description

I tried two setting, for the issue.

No.1 -> it return system default 406 page.

if ($request_method = GET) {
    return 406;
}
error_page 406 /406.html;
location = /406.html {
    root html;
    internal;
}

No.2 -> it will return the custom 406 page

location /test {
    return 406;
}
error_page 406 /406.html;
location = /406.html {
    root html;
    internal;
}

So, could you tell me what are the different between these?

Resolution: invalid

The problem with the first snippet is that return 406 is executed twice:

  1. during initial execution of rewrite module directives specified at server level;
  2. during execution of rewrite module directives for the /406.html (after error_page redirection).

Since the error is returned for the second time, and recursive_error_pages is off, nginx returns an internal version of the error page.

An obvious workaround is to restrict return to a particular location instead of placing it on the server level, as it is done in your second example.

More details about rewrite module directives can be found here.
