Nginx for proxy + rewrite

Hi, List!

I`ve beed using nxingx as a local balancer for few backend servers:

http {
upstream mydomain.com {
server 192.168.8.30; # backend server
}
server {
listen 192.168.10.1:8080;
server_name cmydomain.com;

  location / {
     proxy_pass           http://mydomain.com;
     proxy_redirect       off;
     proxy_set_header     Host $host;
  }

}
}

What I need to do is for a certain url to rewrite it to an external url
but
serve the requests as a proxy instead of returing a redirect, so this is
transparent to the client:

http://mydomain.com/redirect/(.*)$ should go to
http://extranal.comain.com/$1

I saw this is possible with a simple rewrite but it returns a redirect
to the
client. Is is possible to make nginx to server the rewrite as a proxy?

I’m not sure that understand your problem, but this may help:

   proxy_pass           http://mydomain.com;

   proxy_redirect       http://mydomain.com/            /;
   proxy_redirect       http://mydomain.com/redirect/   /;

Or probably, you need X-Accel-Redirect:

This however returns a 302 code, what I want is nginx to get the file
requested from http://some.domain.com/ and server it to the client, so that
the client doesn’t have a clue that this was taken from an external server.
In other words, I`d like to treat http://some.domain.com as a backend server,
but just for a given location.

Hope that makes sense. I don’t think X-Accel-Redirect is what I need here.

I still do not understand your problem. Probably, you need:

location / {
    proxy_pass           http://mydomain.com;
    proxy_redirect       off;
    proxy_set_header     Host $host;
}

location /redirect/ {
    proxy_pass           http://some.domain.com/;
}

What I`m trying to do is to server some location (/redirect/ in the
example
above) to an external server. It is doable with this:

location /redirect {
rewrite ^/redirect/(.*)$ http://some.domain.com/$1
}

This however returns a 302 code, what I want is nginx to get the file
requested from http://some.domain.com/ and server it to the client, so
that
the client doesn’t have a clue that this was taken from an external

Thats exactly what I needed, thanks a lot!
