Never! Never use “if” just to test $host.
There is special very optimized directives server/server_name:

 server {
      server_name  blah1.com  blah2.com;
      rewrite  ^   http://blah.com$request_uri;
 }

So from You are saying is should replace:

server {
listen 8080;
location / {
set $my_host $host;
if ($host ~* “(.+.nl.test.com|.+.test.nl|test.nl)”) { rewrite
^ http://nl.test.com$request_uri last; }
proxy_pass http://apps; proxy_set_header Host $my_host;
}
}

with

server {
listen 8080;
server_name *.nl.test.com test.nl *.test.nl;
rewrite ^ http://nl.test.com$request_uri last;
}

yes?

Yes. And “test.nl” and “*.test.nl” can be combined in one “.test.nl”.

Also you do not need
set $my_host $host;

use just
proxy_pass http://apps;
proxy_set_header Host $host;

It’s working if we are redirecting the traffic to onother domain.

But what i need is something like

    if ($host != www.mydomain.com){
        rewrite  ^(.*)$ http://www.mydomain.com$1 break;
    }

Is there any way to do this?

It’s just question of writing correct server{} declarations.

server {
    listen 80 default;
    server_name_in_redirect off;

    rewrite ^ http://www.mydomain.com$request_uri?;
}

server {
    server_name www.mydomain.com;
    ...
}
