Karl, Kim’s cousin and web developer, makes it onto one of Wired.com’s tech blogs at Monkey Bites : Charles the Debugger with his incredibly useful web proxy debugger and testing tool : Charles : Web Debugging Proxy | HTTP Monitor | HTTP Proxy | HTTPS/SSL Proxy | Reverse Proxy.
One of its features is to allow you to set the web proxy to simulate different network speeds, e.g. 56K modem or 256K DSL, so see how your web site works at those speeds. That’s pretty neat and I would have thought essential for testing the usability of web sites (along with things like testing cross-browser and operating system performance).
I’d imagine it would be extremely useful for testing e-learning system where distance students don’t always have the latest and greatest internet connections.
