Fiddle me this Batman!

I've been working in Internet Explorer land lately.  This is primarily due to contract work on a SharePoint project where the client really only cares about IE working well. (at least for now)   So for all of you Firefox users out there who (like me) are use to have Firebug at your finger tips it can be a little mind numbing to be without a way to see the HTTP traffic in all it's glory.  That's where Fiddler comes in to play!  In fact, it might just replace Firebug altogether for me.  I like the stand alone process approach.  So far Fiddler is footing the bill.  If you're looking for a good Web debugging Proxy that is free then you should give it a try.
