FiddlerCore is a cross-platform .NET library by Progress Telerik which allows capture and modification of HTTP/HTTPS traffic. Some of the most popular applications using FiddlerCore are Telerik Fiddler (.NET Framework-based and running on Windows) and Fiddler Everywhere (.NET Core-based and running on Windows, Mac, and Linux).
This repository contains sample applications demonstrating possible usages of the FiddlerCore API.
Currently the following demo is provided:
The sample demonstrates the following concepts:
- Generate and install unique certificate that will be used for decrypting HTTPS traffic.
- Set proxy allowing to capture all traffic from the machine, and chaining to upstream proxy if needed. Reset the proxy on exit.
- Capture HTTP/S sessions and preserve them in a list.
- Save the sessions in a SAZ (Session Archive Zip) file, a standard archive file which can be password-protected and, if needed, opened later with Fiddler.
- Open a SAZ file and list session information.
If your application is targeting .NET Framework, you can find a demo for the old FiddlerCore version, which supports NET Framework 4.8 (https://github.com/telerik/fiddler-core-demos/tree/v5.0.2)
.NET based application targeting .NET 8 and using FiddlerCore for .NET.
To build the application, you would need the corresponding .NET 8 SDK.
FiddlerCore-related NuGet packages are referenced from the Telerik NuGet server. When prompted for credentials during NuGet packages restore, use your Telerik account through you've obtained FiddlerCore.
Pull requests are welcome! Let's make these samples more understandable for everyone.
