How can I trace the HttpClient request using fiddler or any other tool?

Question

I am using HttpClient for sending out request to one of the web api service that I don\'t have access to and I need to trace the actual request stream getting to the server

Answer 1

If the .NET application is running in your current user account, add the following content inside the configuration section:

Note: Important: Regardless of other settings, .NET will always bypass the Fiddler proxy for URLs containing localhost. So, rather than using localhost, change your code to refer to the machine name. For instance:

This URL will not appear in Fiddler:

http://localhost/X509SignCodeService/X509SigningService.asmx

This URL will appear in Fiddler:

http://mymachine/X509SignCodeService/X509SigningService.asmx
