I've written some applications than heavily use network, and I would like to test it over a slow network. I'm looking for a tool to simulate these kind of connections.
I'm only interested in Windows tools.
I've used Traffic Shaper XP on my XP dev box at work. It seems to handle any connection (not just HTTP). It wasn't perfect, but worked well enough for the tests I was doing. If you're on Windows maybe it'll do enough for you.
