Basically my flatmate often does large http downloads from various sites. I am looking for a way to throttling his http downloads while not affecting his normal browsing experience. I understand Tomato is not effective in inbound traffic shaping. But i am wondering whether I can separate those http downloading connections by checking the amount of bytes it has uploads to the server(i think mainly the ACK packets), ie. set "KB transferred" in QOS-Classification page to be a fairly small value, say 20Kb? Do you think it will work? If anyone has other good ideas, I will also be interested to learn. Thanks in advance.
