Proxy pass / Forward request to specific server according to the Host header on Nginx-CodePudding

so I have an Nginx server. And I'm trying to make it so if the host header is test1.example.com, it will proxy pass / forward the request to the specific IP. How could I do that? I've searched everywhere and can't find anything about it.

This is a repost by the way.

I think what you want can be done using a map:

map $http_host     $my_host_map{
    "foo"         "192.168.1.1";
    "bar"         "192.168.1.2";
    "blort"       "192.168.1.3";
}
server{
    listen 80;
    server_name foo;
    location / {
        proxy_pass http://$my_host_map;
    }
}

with this I can curl my nginx server and set the host in the header:

curl -v --header Host:"blort" 192.168.1.100
