I love the tool Fiddler but the only problem up till now you could not do HTTPS with it but now there is a new plug-in RPASpy!

This could start some interesting discussions with people… <StartSopeBox>Should developers need to look at the HTML stream? The Microsoft tools do a great job of abstracting HTML from the developer. I have seen a lot of developers who don’t know what HTML that gets created for them and it sometimes causes issues around how css works with there pages or how there pages render on non-IE browsers. So my humble suggestion is study your downstream HTML.</StartSopeBox>
