title: How do I use Fiddler to listen to the asp.net development server (i.e. cassini)?
body: <p>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:  "<a href="http://localhost:1066/GeneralService/sections/summary" rel="nofollow noreferrer">http://localhost:1066/GeneralService/sections/summary</a>"  with GET as the http method.</p>
  
  <p>Fiddler responds with "[Fiddler] Connection to localhost failed.<BR>Exception Text: No connection could be made because the target machine actively refused it ::1:1066  "</p>
  
  <p>Is there some way for me to debug an app running on Cassini?</p>
  
  <p>Thanks,
  Steve</p>
