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 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.
