PCRE named captures sill counted in numerical variables list (2 replies)

I tried to configure the following location with something like:

location ~*
"^/([[:alpha:]]{1,8}(?<subtag>-[[:alpha:]]{1,8})?)(/.*[^/])?/?$" {
try_files $uri $uri/ $2/?lang=$1&$args;
}

​However, the $2 variable does not catch the last part of the URI as
expected (either it catches the named capture or nothing at all, that I do
not know nor care).​

​Using $3 instead of $2 does the job.​


​I thought that using named captures allowed for those capture not to be
counted in numerical variable​
​.

​
​Am I wrong expecting that?
