Description

This bug reports comes from a question asked on SuperUser.

For a request to example.org/v3/info.php

location /v3/ {
    alias /var/www/api/v3/html/;
    return 200 "request_filename: $request_filename";
}

produces the right $request_filename = /var/www/api/v3/html/info.php

location ~ ^/(v\d+)/ {
    alias /var/www/api/$1/html/;
    return 200 "request_filename: $request_filename";
}

produces a wrong $request_filename = /var/www/api/v3/html/

That's expected behaviour. In a location defined by a regular expression alias defines full path, so you have to use:

location ~ ^/(v\d+)/(.*) {
    alias /var/www/api/$1/html/$2;
    return 200 "request_filename: $request_filename";
}
