The marketing blitz for Professional Ajax, 2nd Edition has begun. As part of it, you benefit by being privy to free excerpts along the way. The latest excerpt, courtesy of Wiley, is on Ajax Debugging using Microsoft Fiddler. This is a section from the Ajax Debugging chapter of the book. I hope you enjoy it and please send along your comments if/when you pick up the book and start using it.
