Hi,

I’m sticking on configure a reverse proxy, my scenario looks like:

Internet  
…|  
…|\_\_Reverse proxy (listen port 80)  
…|\_\_web1.com (listen port 8080)  
…|\_\_web2.net (listen port 8080)  
…|\_\_web-n.org (listen port 8080)

Assume All website shared one public IP only and each website runs on  
independent VPS.

If I create multi server{} block to use proxy\_pass directive to web  
server inside, it’s only [web1.com](http://web1.com) can be reachable (perhaps it’s on  
top config).

It’s highly appreciate if someone advice me ideas to make this working.

Thanks,

–  
Best regards,  
Hai N., Nguyen

If many backend sites share the same ip, and you refer all of them  
with the same name (or ip) in proxy\_pass directive, you probably  
want to use somethine like

```
proxy_set_header Host <name>;

```

to make sure backend will be able to distinguish them. Or just

```
proxy_set_header Host $host;

```

to pass what you’ve got from client.

Hi Dev,

I’ve followed this document

> **[How nginx processes a request](http://nginx.org/en/docs/http/request_processing.html)**

And I think my problem was missing deffinitions for “www.domain.tld” in  
server\_name; after edit it to

server\_name domain.tld www.domain.tld;

the problem solved.

Thanks for your attention.
