Large file upload with WebSocket

Question

I\'m trying to upload large files (at least 500MB, preferably up to a few GB) using the WebSocket API. The problem is that I can\'t figure out how to write \"send this slice

Answer 1

EDIT : The web world, browsers, firewalls, proxies, changed a lot since this answer was made. Right now, sending files using websockets can be done efficiently, especially on local area networks.

Websockets are very efficient for bidirectional communication, especially when you're interested in pushing information (preferably small) from the server. They act as bidirectional sockets (hence their name).

Websockets don't look like the right technology to use in this situation. Especially given that using them adds incompatibilities with some proxies, browsers (IE) or even firewalls.

On the other end, uploading a file is simply sending a POST request to a server with the file in the body. Browsers are very good at that and the overhead for a big file is really near nothing. Don't use websockets for that task.
