Nginx, how to redirect any requests to the server to a specific URL?

Question

Nginx

How to properly configure Nginx so that when accessing it on port 80 (to any domain), it redirects to a specific URL with passing parameters (URI) and adding UTM tags?

For example, with sourcedomain.com/signup/new , redirect to target.com so that the URL is formed: target.com/signup/new?utm_source=redirect&utm_medium=sourcedomain.com .

It is very important to transfer the domain to utm_medium, so that later you can understand from the analytics which domains you came from.

There can be an indefinitely many domains, and I would only like to limit myself to registering NS records to the redirect server at the registrar once, and not writing anything in nginx itself.

Answer 1

server {
    listen 80 default_server;

    rewrite ^/(.*)  http://target.com/$1?utm_source=redirect&utm_medium=$host;
}
