RIA traffic debugging

Quick note on debugging a Rich Internet Application. As you probably know, RIAs usually don't refresh and communicate to the server in the background. You can't easily see the traffic, so I usually recommend using Firebug for Firefox, Live HTTP Headers, Fiddler, and my recommendation, Service Capture.... Well, there's a new kid on the block ... not so new perhaps, but I just finally tried it and I'm loving it. Charles is another http/amf monitoring application with many more capabilities than service capture ... actually, forget about the capabilities, the fact that I can open it with Firefox with no problems should be enough ... but if that's not enough, you can see the traffic is a structured view instead of sequential, which allows you to see the requests by domain, then folder, then file, and it even groups all the flash remoting calls together ... it's a beautiful thing. In addition it does have more capabilities such as seeing cookies, request / response sizes, mirror responses to disk, analyze cache, bandwidth throttle, spoof dns, and port forwarding. I'm very impressed.
