Build a Custom Inspector
Create a Fiddler Classic extension project.
-
Change the code to derive from the Inspector2 class and implement either IResponseInspector2 or IRequestInspector2.
using Fiddler; [assembly: Fiddler.RequiredVersion("2.3.0.0")] public class WebViewer: Inspector2, IResponseInspector2 { public WebViewer() { // // TODO: Add constructor logic here // } }
Inside the class, create a new method. By typing public override, you'll get an autocomplete list of the methods you need to write.
In Solution Explorer, right-click on the project and click Add > User Control.
Use the Toolbox to add controls to your user control. These will show the data about the HTTP message under inspection.
In the body{ set } and headers{ set } properties, you should update your control's visual representation of the request or response.
