How do I use Fiddler to listen to the asp.net development server (i.e. cassini)?

Question

I am attempting to debug a (RESTful) WCF app using Fiddler. I run my project via VS IDE - which launches my app in the ASP.NET Development Server aka Cassini. I then launch Fiddler and in the Request Builder tab enter the following: "http://localhost:1066/GeneralService/sections/summary" with GET as the http method.

Fiddler responds with "[Fiddler] Connection to localhost failed.
Exception Text: No connection could be made because the target machine actively refused it ::1:1066 "

Is there some way for me to debug an app running on Cassini?

Thanks, Steve

Answer 1

One neat trick is just to add a period(.) after the word localhost. No other config neccesary.

Answer 2

Change the url to http://ipv4.fiddler:1066/GeneralService/sections/summary to enable fiddler to listen on localhost
