John, doesn't HTTP generally run over TCP? What happens when the router
randomly start dropping packets for a TCP connection? Or a little less
orthodox: What happens if the router starts to duplicate ACKs? (Hint
<http://en.wikipedia.org/wiki/TCP_congestion_avoidance_algorithm>)
However, the best solution is probably just to buy more bandwidth.
