FWIW when I debug this sort of thing I like to emit a response header identifying which rule is routing the request, like this:

location /a/ {
add_header X-nginx-debug /a/
proxy_pass http://whatever/;
}

That way you can use F12 tools or some other inspection on the result and see exactly what is triggering. This has saved my bacon more than once ☺.

Hi Francis,

many thanks for your response and guidelines. Indeed you were right that there was another location capturing the request.

Best regards,

This seems to work as expected for me, using nginx/1.14.0.http://1.14.0.

Why do you think it does not work? What is the input/output/expected
output?

For example, if you add the new location

location = /web/foo.do {
return 200 "$uri$is_args$args\n";
}

and repeat the tests, do you see any difference in output?

> Why if I put a number after a hyphen the regex stops working?

My guesses are:

* you have another location{} that you have configured to match those
requests, so your shown location{} is not involved

or

* your /web/foo.do location-handler handles those requests differently.

Good luck with it,
