I need to have my application upload files to another backend, so I thought I could use proxy pass, and have a certain URL be proxied to another machine (proxy_pass http://upstreamserver.com:8080/API/import) . The URL would be http//portalvm/API/upload/ that I upload to.

Actually that is my bad, as I didn't want to expose the server I was using to the whole world.

Host: upstreamserver.com:8080

Will do.

I don't need as far as I know to send the Cookie and Referer to the upstream server, but the content-length is needed for the file I think.

I have actually got it working when I removed a header "INDEX" that was getting sent.
