Thanks Maxim,

using named captures it exactly what I did. The question to me was more
or less if the other configuration was intended to break. If that's the
case, that this is mainly a documentation issue which should be added to
either [1] or [2] (best with cross reference to each other).

[1] http://www.nginx.org/en/docs/http/ngx_http_core_module.html#alias
[2]
http://www.nginx.org/en/docs/http/ngx_http_core_module.html#location

The topic "named captures" is as far as I can see is only mentioned in
[3]. It might be good to demonstrate its use in a wider context. While
doing so, also a comment on the syntax might be great, as PCRE not
always supported the Perl-style notation of "(?<name>)" [4].
