Fiddler lets you inspect traffic, set a breakpoint, and 'fiddle' with any incoming or outgoing data. Fiddler includes a robust event-based scripting system that can be extended using any .NET Framework language.
Easily edit web sessions: simply set a breakpoint to pause processing of the session and then authorize alteration of the response/request. You can compose your own HTTP requests and then run them via Fiddler.
Fiddler allows you to see the “total page weight.” Also, it lets you see HTTP compression and caching at a glance. In fact, you can isolate performance bottlenecks with simple rules such as “Flag any uncompressed responses larger than 35kb.”
Fiddler decrypts HTTPS traffic and displays and modifies web application requests using "man-in-the-middle" decryption techniques. You can configure Fiddler to decrypt all traffic or only specific sessions that you need. Benefit from rich extensibility modeling, that ranges from simple FiddlerScript to very powerful extensions that can be developed using a .NET Framework language.
Fiddler ensures that proper headers, cookies, and cache directives are transferred between clients and the server.
