Ngnix forward url from first server to second

Question

I have two servers.

Server 1: 185.185.xxx.xxx (this is the main server with domain mydomain.com)

Server 2: 176.28.xxx.xxx

On the first server I added A zone

A   cdn    176.28.xxx.xxx

When I type cdn.mydomain.com this link will open 176.28.xxx.xxx (I'm already set host) And this is working fine.

WHAT I NEED

When user type mydomain.com/cdn I need to open same as cdn.mydomain.com (on second server)

example

user type: mydomain.com/cdn/myphotos.zip

need to open: cdn.mydomain.com/myphotos.zip

How to set this?

I'm trying, but no luck. I'm have Ubuntu and Nginx. No Apache. I'm need config for ngnix. Can anybody help me? Thanks

You can use a map to capture the path relative to the cdn directory on Server 1 then define a variable that points to the same file at the root of Server 2.

Maps are evaluated early in the nginx cycle and are a good place to use regular expressions.

map $uri $cdn_uri {
    ~^/cdn/(?<path>.+) $scheme://cdn.mydomain.com/$path;
}

If the $cdn_uri variable is set, redirect to it on Server 2.

server {
    # Server 1

    if ($cdn_uri) {
        return 301 $cdn_uri;
    }
}
