New Fiddler Betas

New beta versions of Fiddler and Fiddler2 are now available. These betas are tracked to be promoted to the official "Ship" versions and deployed to a huge number of machines via autoupdates... unless bugs are found. Please send any issues you find my way ASAP.

Both releases include a number of minor bugfixes, and the first basic implementation of the AutoResponder tab, which allows easy manipulation of HTTP requests using locally-altered files from your \Captures\Responses folder.

Fiddler2 also includes the first basic support for the IAutoFiddle interface, a new extensibility model that enables powerful extensibility via .NET; IAutoFiddle will eventually allow you to create drag/drop libraries of manipulations that can easily be shared without manipulating your Custom Rules file. Expect to hear more details about IAutoFiddle over the next few months.

Thanks for your continued interest!

Fiddler hits the books

I didn't notice until recently, but it looks like a few books on web development now recommend Fiddler and explain how to use it. It's also been mentioned in a few magazines around the world.

If you see Fiddler mentioned in a book or magazine review, please drop me a note!

Thanks,
Eric
