Routing to different servers with nginx

Question

Is there a way to use nginx as a router while keeping the requested domain in the URL? For example, if I hit mysite.com, the nginx routing server looks at the URL and directs traffic to a particular server, all while maintaining the original requested domain in the URL.

E.g.

mysite.com/site1/params
Router -> site1.mysite.com/params

But even though behind the scenes site1.mysite.com/params is being called, the user sees mysite.com/site1/params in the URL.

I've taken a stab at the configuration, but seem to be getting 404's.

upstream site1 {
  server site1.mysite.com;
}

location /site1 {
  rewrite ^(.*)$ /$1 break;
  proxy_pass  http://site1;
  proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
  proxy_redirect off;
  proxy_buffering off;
  proxy_set_header        Host            $host;
  proxy_set_header        X-Real-IP       $remote_addr;
  proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
}

Use location with trailing slash, remove rewrite and use proxy_pass with / uri. Nginx will take of replacing /site1/ with /. Also, you may need to set Host header to site1.mysite.com not the $host.

location /site1/ {
  proxy_pass  http://site1/;
  proxy_set_header Host site1.mysite.com;
  ...
}

This seems to redirect me to mysite.com:random-port – bswinnerton Mar 27 '14 at 14:30
Just in addition to my last comment, it works if I manually type in port 80 to the initial URL, is there any way to get around that? – bswinnerton Mar 27 '14 at 14:39
You should put port to upstream definition `server site1.mysite.com:80;` – Alexey Ten Mar 27 '14 at 14:44
Yeah, same issue when I try that : /. Perhaps it's cached. – bswinnerton Mar 27 '14 at 14:45
Oops. Port 80 is default. Try to clear browser cache – Alexey Ten Mar 27 '14 at 14:46
That worked! One last quick question, how can I make sure that params get passed in as well? Would that be in the `proxy_pass`? – bswinnerton Mar 27 '14 at 14:54
They are proxied by default. – Alexey Ten Mar 27 '14 at 15:11
