The new Fiddler Beta has a few useful tricks. First, you can copy a DataURI to your clipboard (from Fiddler itself, or anywhere else):

and use the new Edit > Paste Files as Sessions command:

… to instruct Fiddler to parse the DataURI and create a new Session for it. You can then use Fiddler’s inspectors to examine the resulting object:

Next, the WebView Inspector has been enhanced to render previews of WOFF font, MP3 audio, and H264 video responses, if you have IE9+ installed:

Lastly, Fiddler’s AutoResponder now permits you to use Regular Expression Group Replacements to map one URL to another. For instance, this rule:

…will convert http://somesite.com/assets/Test1.gif to http://www.example.com/mockup/Test1.gif. This capability makes it even easier to replace content using Fiddler’s AutoResponder.

 

This new build of Fiddler has a ton of other fixes and performance improvements. I hope you enjoy it!
