Nginx: how to set up a redirect by subdomain and request_uri?

Question

Nginx

Good evening!

Can you please tell me how to configure the following condition in nginx:

if ($host = sobdomain.domain.com) {
  if ($request_uri = ^\/(login|signup)$) {
    return 301 https://other.site
  }
}

That is, provided that a certain subdomain and a certain URL are used, redirect to another site.

Answer 1

map $host$request_uri $_url {
    ~^([^?]*)  $1;
}

server {
    if ($_url ~ "^subdomain\.domain\.com/(login|signup)$") {
        return 301 https://other.site/;
    }
