Fantastic Igor - I didn't know that you could do named captures in Nginx
-
good to know.

That solves it rather nicely.

And thanks B.R. - yep, that syntax is part of PCRE.

Yup the location directive uses the PCRE library to interpret regex.
Its docs doesn't mention that the regex are PCRE, but the hint is given
away on the build from sources
<http://nginx.org/en/docs/configure.html>page.

It reminds me that not so long ago I mixed up named captures and
subpatterns syntax trying to play with PCRE in location... but that is
another story ;o)

Glad I could help!
