nginx에 대해 임의로 헤더의 호스트가 변경됩니까?

하나의 웹 사이트와 하나의 URL을 형성하는 많은 서버에 액세스하기 위해 nginx가 예약 프록시를 만들어야합니다. 예를 들어 나는이 URL에 의해 nginx를 하나의 사이트를 만들 필요가 : www.main.com 많은 다른 사이트의 서버를 통해 리디렉션됩니다nginx에 대해 임의로 헤더의 호스트가 변경됩니까?

www.server1.com

www.server2.com

www.server3.com

이러한 서버가 바쁜 몇 번 있습니다

...

그래서 그 바쁜 서버로 리디렉션하고 무료 서버 대신 리디렉션에 대한 거부해야합니다. 무작위로 또는 어떤 변수 유사하여 SO

책임에 TIME_OUT하고 ...

그래서 내가 proxy_pass에 대해 KNW이이 코드에 의해 작동을 위해 내가 한 유사한 사이트를 만들어 :

의 작업 만이 개 목록 사이트에서 첫 번째 사이트로 리디렉션 :

상류 인덱스 {

server diy-tornado4ss.rhcloud.com; 
    server diy2-elasa2.rhcloud.com backup; 
}

와 사이트는 추가됩니다 diy-tornado4ss.rhcloud.com로 리디렉션 :

location ~* ^/(.*) { 
      #root html; 
      #index index.html index.htm; 
      proxy_set_header Host diy-tornado4ss.rhcloud.com;

로 proxy_set_header 호스트을.

그래서 어떻게 내 목표에 도달 할 수 있습니까?

감사합니다.
