How to use JavaScript to stream parts of a file?
<p>Given a really large, 3+ gig, binary file is there anyway that I could stream, from client to server, only portions of the file using JavaScript given that I know what byte range of the file that I want to receive?</p>

<p>I have a Ruby on Rails application that needs to grab specific portions of a file from the client. As one user has stated I could do this using Java.</p>

<p>Edit: After some reading it appears that HTML5 via slicing a file may be the best bet. <a href="http://www.html5rocks.com/en/tutorials/file/dndfiles/" rel="nofollow">http://www.html5rocks.com/en/tutorials/file/dndfiles/</a></p>
