Can you provide a little more detail on how it's implemented?
Are you using resumable.js[1] or is it a custom implementation?

Sure, let me give some further implementation detail.
We were inspired by https://github.com/dmitry-dedukhin/lightweight-uploader, particularly the js implementation from Dmitry.
It turned out, however, that the simple flow control he implemented was not adaptive enough to simultaneously accommodate both low-latency/low bandwidth and high-latency/high-bandwidth connection.
For resumeable uploads to work efficiently for both cases, we implemented TCP/IP-style congestion control (e.g. slow start window size scaling and exponential back-off retry timeout), but over http POST requests instead of UDP packet sends.

Amazing! I thought it's a desktop tool only feature. Really nice to see this feature finally available on web. I'm wondering why it's available on Chrome and FireFox only. How about IE9?

If you use Chrome or Firefox, you can now drop a file onto a page on minus.com, unplug your network, reconnect, and your file resumes uploading where you left off.
I love the web and am excited to see the range of possibilities for pure-browser features expand.
