As an example I want to redirect "/آرایشگر" to "/استخدام آرایشگر" and I am using a rewrite rulr like the one below but things go wrong and I get a 404.

rewrite_rule: rewrite ^/آرایشگر/$ /استخدام آرایشگر;

And what do you mean by config? Do you mean nginx settings or configurations at compile time?
