title: Intercept HTTP Traffic from browser and show the headers in c#
body: <p>I need to create a c# application that intercepts http traffic from the user's browser (Firefox, chrome) by adding proxy settings in the browser and then show the HTTP headers of the request without using any third party plugins like FiddlerCore.</p>
  
  <p>I found some examples using HttpListener but none of them show the headers.</p>
