Debugging the Web with Fiddler

Every web developer encounter in their work the need to see what goes on "in the wire", whether it is an AJAX call in ASP.NET, a WCF service call from Silverlight, or a simple postback for an ASP.NET web page. With Fiddler, the most famous HTTP sniffer, this is simple enough to do. Fiddler is more than just a sniffer; with Fiddler you can intercept, alter, and record messages. You can even write your own visualizers that display the content of the messages according to its meaning (video, image, XML, JSON …).In this session we will learn how to use Fiddler from bottom to top to make our debugging routine easier.
