title: Uploading files in Ruby on Rails
body: <p>I have a web application that needs to take a file upload from the user and upload it to a remote server.  I can take input from user to server fine via file_field, but can't seem to work out the next step of uploading from server to remote.  Net::HTTP doesn't do multipart forms out of the box, and I haven't been able to find another good solution.  I need something that will allow me to go from user -> server -> remote instead of going user -> remote.  Anyone succeeded in doing this before?</p>
