title: Sending actual destination path from nginx module to backend
body: <p>For uploading a file to a server I am using nginx upload module. What I understood from the docs is that it saves the uploaded file to a temporary directory and only provides information about the file to backend(python bottle server in my case) via POST and information that should be passed to backend can be specified by upload_set_form_field directive.</p>
  
  <p>How can I send the actual destination path to backend ,Since nginx will store in some temporary path and not to the path where the uploading was meant to? </p>
