title: Does the current NGINX have some kind of buffer support for uploading large files?
body: <p>I am writing a ruby on rails application that has large file uploads. (20-100MB). 
  I have looked into ways to do this without tying up the rails processes. I have come across an nginx module that does specifically this. (http://www.grid.net.ru/nginx/upload.en.html)</p>
  
  <p>However, It seems to me while watching logs and my server that while uploading a large file, it seems to buffer before sending over to my rails process..even without the nginx module upload module installed.</p>
  
  <p>My QUESTION then is: It seems like nginx is doing this by default install... Do I still need to install and use the upload module? What is really going on here? </p>
