  • 0

This is sort of a theoretical question, however, I need to add file sharing capabilities to my web socket powered chat application. I could use a service like Amazon S3 to upload a file to share by posting a link to the file, but that involves the uploading of a file that may already be accessible over the local network (sharing a file between co-workers for example).

So I had the idea that it might be possible to somehow tunnel the upload/download/transfer through the already existing web socket connection. However, I don’t know enough about HTTP file transfer to know the next step of how to implement it. Is there a limitation to web sockets that would prevent this from being possible?

I’m using Ruby and EventMachine for my current web socket implementation. If you were able to provide a high level overview to get me started, that would be very much appreciated.

    To allow files to be shared without the need to upload it to the server, (i.e Coworkers) you can now use the WebRTC DataChannel API, to create a peer to peer connection.
