如何使用nginx作为反向代理将localhost：9292定向到子域foo.localhost /？

Question

I've learned how to pass localhost:9292 to localhost/foo with the following directive:

location /foo {
    proxy_pass http://localhost:9292;
}

but I want do something like

foo.localhost -> localhost:9292

Is there a way I can do that?

If foo.localhost is your sub domain name and you want to proxy pass sub-domain to main-domain, you can use proxy_pass and you can learn a little more about server directive if needed. An example:

server {
  listem 8080;
  host sub.main.com;
  ...
  location / {
    proxy_pass http://main.com;
    break;
  }
}
server {
  listen 8081;
  host main.com;
  ...
  location / {
    //do something
  }
}

This is proxy pass, means when access sub.main.com, actually it finally dealt by main.com, but the client side still shows sub.main.com. If you want client side shows main.com, here should use redirect but not proxy_pass.
