title: how to write a file object on server response and without saving file on server?
body: <p>I am using Spring with DWR . I want to return a file object as response , however I save the file (to be sent) at server temporary location and then send its location as href for anchor tag on client side , however I wonder if there could be a way to throw the file directly to browser on response object without saving it temporarily on server.</p>
  
  <p>I expected if there could be a way to send file as a response via DWR.</p>
