Every web developer needs to see what goes on "in the wire," whether it's a jQuery call from JavaScript, a SOAP or a REST service call from a client app, or a simple GET request for a 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, record messages, and even write your own message visualizer.

In this session, you'll learn how to use Fiddler from bottom to top to monitor, debug, test, and improve web applications. You'll also check some of Fiddler's newest features, such as the WebSocket viewer, single-session timeline, and direct session filters.

You will learn:

  • How to monitor web traffic
  • How to debug web applications
  • About Fiddler's new features
