convert rule apache to nginx

[VovansystemS]

> RewriteCond %{REQUEST_URI} /(.+?)/pagina-(.+?)/ [NC]
> RewriteRule (.*) /%1/?page=%2 [L,QSA,NC]
итак,
[NC] -  (no case) - без учёта регистра
[L] -  last|L	- Stop the rewriting process immediately and don't apply
any more rules. Especially note caveats for per-directory and
.htaccess context
[QSA] - qsappend|QSA - Appends any query string from the original
request URL to any query string created in the rewrite target.
[NC] - nocase|NC - Makes the pattern comparison case-insensitive

значит, должно быть как-то так:
rewrite ^(/.*)/pagina-(.*)/ $1/?page=$2&$args break;
но такая конструкция получилась чувствительной к регистру

лучше так:
location ~* ^(?<x>/.*)/pagina-(?<y>.*)/ {
    rewrite ^ $x/?page=$y&$args break;
}
