title: Upload big file on Rails-API
body: <p>I wonder how manage on a rails-api the upload of a "big" file (arround 100m). Is it possible to stream to s3 the rack tempfile during the upload?</p>
  
  <p>I'm creating a new service how just need to receive post request with parameters and files ask the original app if it's everything is ok, and process them. Lot's people over blogs tell that ruby is not the best language for that, it's not a problem to change.</p>
  
  <p>So I would like to know if making a rails api who will received post, return status, and communicate with the other rails app is a good thing. </p>
  
  <p>Thanks in advance</p>
